Welcome to Brad's online memory archives.

Unit Cost

I use a lot of cleaning wipes in my classroom, so I frequently need to re-stock. Yesterday I stopped to get some, and was trying to get the best value for my money. They come in a lot of differently-sized containers with different prices. I just used my phone to divide the price by the number of wipes to find the price-per-wipe.

The best value was surprising – it was the smallest containers in a multi-pack. Just above them on the shelf were the biggest containers, but they were fifty-six cents more expensive. I’m pretty sure six smaller containers means more plastic in the landfill than two larger containers, so I did hesitate a little, but some day it will make the landfill-miners glad to find more complex petrochemical compounds in their haul.

I got two three-packs.

    Ha! Your logic and calculations break my heart, but it’s true. WHY, companies? WHY? It makes no sense!

    It is always cheaper per ounce to buy the single smaller size speed-stick deodorant than to buy the 2-pack of the larger size at The Wal-Marts. It used to upset me each time I would see it. Now I consider it a tax on people to dumb or lazy to do the math. I like to think that the extra profit from the larger size goes to subsidize my stinky needs.
