Why do stores (all-inclusive, from Kroger to Walmart) bother with the Unit Price section of price labels on shelves? They obviously don't want consumers to be able to use this information. Anyone who has read these labels has seen what I'm talking about. The unit price for brand/size A is listed in liters, but brand/size B is listed in ounces. I've also seen them have an actual measurement on one, and per each (i.e. a six pack of cola or beer). But today I saw the most useless unit price ever. It was a label for a package of 6 candy bars at Walmart. The unit price was $48.76 per 100 bars. Sure I can do the easy math and figure it out per bar, but who goes into Walmart and buys 100 of a single type of candy bar?
