09:33 – I just shipped the last biology kit we had in stock, but I have another 30 in progress. I should be able to finish those today or tomorrow, depending on what else comes up. We’re also down under two dozen chemistry kits in stock, so I need to get another batch of 60 of those started.

In 2013, my goal was to double 2012 revenue. We didn’t quite make that, finishing 2013 at about 185% of 2012 revenue. Starting 2014, my goal was to double 2013 revenue. Through today, we’re running about 170% of January through May 2013 revenue. Of course, it’s the quarter covering July through September that will determine our year’s results. Last year, our revenue for that three month period matched the other nine months combined. And we did about a quarter of the entire year’s revenues just in August. Which is why I’m working hard to get finished-goods inventory built up in time for the rush.


12:35 – Using stamps.com rather than USPS Click-N-Ship just saved me $3.04. The USPS web site doesn’t offer first-class parcel as an option, and the least expensive Priority Mail option is $5.05 for a small flat-rate box. So I used the stamps.com software running on the Dell Windows 8.1 laptop to print a first-class parcel label for $2.01 to ship a four ounce box.

Stamps.com supposedly supports Linux and Mac clients via a web-based app. I couldn’t get that to work with my main system when it was running Linux Mint, but since I’d upgraded it to Ubuntu 14.04 LTS, I decided to give it another shot. It worked fine, right up to the point where I tried to print the postage label. A box popped up telling me that I had to install a small app before I could print postage. That app is a Windows .exe file. So much for supporting Linux and Mac clients.

So I fired up the laptop and ran the stamps.com software. Everything proceeded smoothly until I tried to print the postage label. When I did that, a box popped up warning me that I was using the “hide postage” option. Apparently, the USPS is very sensitive about that. The box warned me that if the weight was incorrect or there was any other significant issue, USPS would probably revoke my hidden-postage privileges. Okay, so I clicked on the button to show postage. The app then popped up another box that asked if I was really sure I wanted to show the postage amount on the label because hiding postage improves deliverability. Eh? No matter which of their suggestions I accepted, I’d be violating the other. So I chose to hide postage, just to see what the label would look like. The package, hidden postage and all, is now sitting in the queue to be picked up. If the Postal Police come after me, they’ll never take me alive.

10:35 – Barbara is starting her 4-day week, which she says always seems longer than a regular 5-day week. I’m doing admin stuff and building some biology kits.

Our food storage project is progressing. Yesterday, I decided to check the lds.org site to review their recommendations. I was surprised to see that they’d entirely revamped their suggested food storage, apparently back in 2008. They used to recommend a one-year supply of food, mostly dry grains and beans and so on. They now recommend a 3-month supply of canned goods and other foods you regularly eat, along with a one-year supply of the long-term storage stuff. They’ve also hugely increased their shelf-life estimates for many products, although they’re still far too pessimistic about many items. For example, they list white sugar properly stored as being good for 30 years, when 300 years is more like it, if not 3,000.

Also, I either never knew or had forgotten that lds.org has a physical store out near the airport, about half an hour’s drive from us. They carry lots of stuff in #10 cans for long-term storage, and the prices are quite reasonable. Their hours are quite limited–9 hours a week or so–but they are open the 2nd and 4th Saturdays of each month from 9:00 a.m. to noon. And they’re happy to sell products to anyone rather than just church members. I guess their attitude is that the more people who are prepared for emergencies, the better.

07:35 – Barbara is taking today off work. With the holiday Monday, that gives her a four-day weekend. We’d planned to sleep in this morning, but Colin woke us at 6:15 vomiting. At least he wasn’t up on the bed at the time.

Barbara has lots of work planned for the next few days, including painting the new columns on the front porch and the new threshold at the back door. I hope we can keep Colin away from the wet paint. Over the years, our experience with Border Collies and wet paint hasn’t been good.

There’s an article in the paper this morning about state government subsidies for movie and TV production companies. North Carolina has been a major participant. Most of the action takes place in Wilmington, where many TV series have been or are being produced, including Dawson’s Creek, One Tree Hill, Hart of Dixie, Under the Dome, Revolution, Sleepy Hollow, and Eastbound and Down.

But now many states are rethinking these tax breaks and production credits, wondering if they’re getting enough bang for their bucks. Many states are eliminating subsidies entirely. North Carolina is tweaking the rules, eliminating subsidies for talk shows and sporting events and focusing more on credits for building production facilities and other infrastructure. I suspect that North Carolina has already reached critical mass, with major production facilities already located here, a continuing flow of talented and skilled graduates from Winston-Salem’s North Carolina School of the Arts, and our generally low cost of living.


09:16 – In terms of physical components, chemicals are by far the largest cost item in our kits. The chemical cost for a bottle ranges from a few cents to a few dollars each, depending on the chemical. But the second largest cost item for physical components is the containers themselves, which range from about $0.15 to $0.90 each. That may not sound like much until you realize that one kit may contain 50+ containers.

Until recently, I’ve been happy with our primary container supplier. Their prices are competitive, they stock most of the containers and caps we need, and they ship quickly. They also provide free ground shipping on any order of $250 or more, which isn’t a problem for us. But I’m starting to worry about them. In the past, I’d place an order with them and it would be shipped the same day or the following day. I’d generally receive it two or three days after I placed the order. But on the last couple of orders they’ve been much slower to ship. It’s not a backorder problem. When I placed those orders, they showed all items as in-stock. But rather than ship the same or the following day, they’re now taking five to ten business days to ship. In one sense, that’s not a big problem. I always keep reasonable stock levels of the containers we use. But I do wonder what’s going on with them.


11:44 – Amazon just added a new benefit for Prime members, called Amazon Prime Pantry. They charge $6 for shipping, but that’s for a very large box. Adding a Prime Pantry item to your cart starts a new box. Each Prime Pantry item states how much of a box it fills. If you exceed the volume or weight capacity of the box, it automatically starts a new box.

So I started playing around with it, just to see how much would actually fit in the box. I’m still building our long-term food storage (as opposed to just the car emergency kits). Lipids are an issue for long-term storage, and one of the best ways to store lipids is canned Crisco. The manufacturer says Crisco remains good for at least two years, but in fact an unopened can will remain good for at least ten years, and probably a lot longer. We don’t routinely use Crisco here, but Barbara frequently uses vegetable oil for frying chicken, stir-fry, etc. Crisco works just as well for that as liquid oil, so I decided to add some Crisco to the box. (Incidentally, canned Crisco is also excellent for emergency lighting. Sticking a piece of string in a can gives you an emergency candle that’ll burn all day long for literally a month.)

Despite Python, I happen to like Spam canned meat, so I added a few cans of that as well. I ended up with 11 48-ounce cans of Crisco and 14 12-ounce cans of Spam in that one box. Amazon informed me that my box was 100% full and asked if I wanted to check out.

I typically place several Amazon.com orders per month, and every time it offers a discount if I apply for an Amazon Visa card. I finally decided to click on the Learn More link, and I liked what I saw. I’d been using our Costco AmEx card at Amazon. It provides a 1% rebate on all purchases, with a higher percentage for Costco purchases. The Amazon card provides a 3% rebate on Amazon purchases, and lower percentages on non-Amazon purchases. So I filled out the on-line application, asked for a second card for Barbara, and clicked Submit. After about 10 seconds, the screen refreshed and said the card was approved and that it had been set as our default payment method for Amazon purchases. It also said I’d been issued a $60 credit that would be applied automatically to our next Amazon order unless I told them otherwise.

Given that we make a huge percentage of our purchases from either Costco or Amazon, it makes sense to have a stored-branded card for each. We already have a Visa card from our credit union, but it’ll be easy enough to cancel that. The new card has only a $5,000 credit limit, but I’m sure we can get that increased if we need to.

09:16 – Darrell Issa is still pushing for USPS reform. His latest bill in committee would end door delivery for 15 million addresses over the next 10 years, substituting curbside or communal boxes. At the stated cost annually per address of $380 for door delivery versus $240 for curbside versus $170 for communal boxes, the cost savings could be substantial. The articles I’ve seen state that USPS would pay all costs for the change, but I doubt that. I’m sure they’ll pay to install communal boxes, but I don’t see them paying to install curbside boxes at individual homes. Actually, they should. Assuming their numbers are accurate, replacing door delivery with a curbside box saves $140 per year, every year. If it costs $140 to install a curbside box, they’d pay off that cost in one year and then save $140/year every year thereafter.

Actually, I suspect they’d save more than $140/year when you consider the improved fuel mileage and reduction in maintenance costs on their vehicles. Nationwide, those LLV USPS vans are started and stopped literally billions of times a month. They must go through a metric boatload of new starters every year. And, although I’d be annoyed at being forced to pay for a curbside box and installation, otherwise I’d have no problem with shifting to curbside delivery. Obviously, I wouldn’t be able to fit outgoing kits into a curbside box, but I could just make up a laminated sign to hang on the flag and train the carriers on our route to come to the door when I had outgoing packages.

I’m still building kits and filling bottles. Sales are still slowish, but starting to pick up. Starting in mid-July, only two months from now, things will start to get crazy, so we need to be ready.

09:37 – We’re getting low on biology kits, so I’ll get started on a new batch today. We got a good start last weekend on cleaning out the upstairs work/inventory room. Once we finish that, I’ll have room to store a couple hundred or more kits there.


14:03 – I found this surprising: Only 56 percent of Americans can perform the five core swimming skills

The article notes that 86% of Americans believe they can swim, which apparently means that 30% of the people you encounter believe they can swim, but can’t. Hmmm. I believe I can swim, but perhaps I’m wrong. I learned to swim before I started elementary school. Our junior high school had an indoor pool, and half our gym classes took place in the pool. In high school and college I spent lots of time every summer swimming and diving, and I passed the Water Safety Instructor test in college. But I haven’t tested the hypothesis in probably 35 years or more, so perhaps I’ve actually forgotten how to swim.

But apparently nearly half of Americans lack even basic swimming skills, which is disgraceful. How can parents not teach their children to swim? How can schools not require that children demonstrate the ability to swim? Talk about a fundamental skill. If in fact 44% of Americans can’t swim, I’m surprised that only 10 people a day drown in this country.

08:16 – We’re apparently getting a new mailman. Danny Hughes, who’s been our carrier for the last couple or three years, started working a new route yesterday. Tammi, Danny’s regular replacement, told me that she wasn’t completely sure who’d be the new regular carrier, but the one she expects to get this route is a good one. I’ll have to get him used to picking up a lot of packages here.

I’m still building up inventory by filling bottles. Lots and lots of bottles. When I finally get through this latest batch, we’ll have enough for 60 forensics kits, 90 biology kits, and 150 chemistry kits.

09:18 – Dentist yesterday. I was home by noon, and decided that I had time to get postage labels printed for the 30 kits stacked up waiting to ship. I’d been using the USPS Click-and-Ship website successfully to print postage labels for a week or more, but of course this time it decided not to cooperate. So I fired up the Stamps.com software and used it to generate and print postage labels.

We’ve had a month’s worth of rain this week, with more to come tomorrow. While I do laundry this morning, Barbara’s heading out to do yardwork before the rain shows up.

09:21 – I have those 30 kits boxed up and ready to ship. I started with filled and labeled chemical bottles, but otherwise I built those kits from scratch in two busy days. That tells me that without additional labor we can build at least 30 kits a week every week if we need to, or about 1,500 kits per year. That’ll do for now.

That leaves storage as the only issue. Barbara nixed the idea of parking my Trooper outside. She doesn’t want it sitting out in the weather. As an alternative, she suggested expanding our storage area into the finished area downstairs. That’s fine with me. That means I can get most of the stuff out of the work/storage room upstairs and use it mostly for finished goods inventory and partially as a staging area for building kits. Bulk stuff like cases of bottles, beakers, tubes, etc. can go into the finished area downstairs. Problem solved, at least for the next year or two.

09:54 – Yesterday, I finished making up all the subcomponents for 30 chemistry kits, including 30 shipping boxes. Today, I’ll get those 30 kits boxed up and ready to ship.

When we started this business, I expected to sell science kits almost exclusively to homeschool families, with perhaps a few being purchased by DIY science hobbyists, private high schools, homeschool co-op groups, and so on. It turns out that our potential market is a lot broader than I expected. We’ve sold kits to many public high schools, community colleges, and four-year colleges and universities, as well as local, state, and federal organizations. It appears that our potential market is easily ten times the size I expected, and could very well be 100 times or more. Rather than selling hundreds of kits per year, we could be selling thousands. Assuming that we want to do what it takes to do that.

We made three decisions starting out: we didn’t want to borrow money, rent space, or hire employees. I still don’t want to do any of those, but I realize that those decisions limit us to shipping perhaps 1,500 kits per year, and that’s working flat out on building and shipping kits, leaving no time to do anything else.

I still don’t intend to borrow money, ever. I don’t want to be beholden to a bank, and we can easily fund reasonable growth from cash flow. Space and labor are another issue. Eventually, if we want to continue growing, we’re going to have to rent or buy space and hire employees. Right now, space is the main constraint. And that’s easily solved for now. I can simply park my Trooper at the end of the drive and use the space that frees up to install industrial shelving for storing raw materials, component inventory, and finished-goods inventory. As to labor, we can make do for now. If necessary, we can subcontract out some of the time-consuming stuff, like labeling bottles. Eventually, when Barbara retires, she’ll be able to put in more time on kit stuff. But I don’t doubt that the day will come when we’ll have business premises and hired employees. I’m really not looking forward to all of the hassles involved in doing that.

Meanwhile, we’re going to do some stuff aimed at increasing sales to public schools, universities, and so on. The first thing is accepting purchase orders, which we’ve already started doing. The second thing is designing and building classroom kits. A course-based classroom kit doesn’t differ much from our current individual kits. It’s simply designed to support four workgroups rather than just one for a lab course that covers an entire semester or year. Topic-based classroom kits, which we’ll also eventually create, are different. Rather than cover, say, a year-long first-year chemistry lab course, a topic-based kit covers only a particular topic, such as chemical equilibrium, forensic blood analysis, or photosynthesis and respiration in plants. Topic-based kits make it easy for a teacher to pick and choose the topics to be covered.

09:33 – Yesterday, I binned and bagged 30 sets of unregulated chemicals for chemistry kits, and binned 30 sets of regulated chemicals. I’ll bag those today, make up 30 small parts bags, tape up 30 boxes, and start building the kits. I also need to make up four liters of iodine solution, which we’re running short of.

I also spent a lot of time yesterday getting my main system configured, restoring data, and so on. Everything works now. I’m content with Ubuntu 14.04 LTS, which is good considering that I intend to continue using it for the next five years. I already like it better than I did Linux Mint 15.
