I can cite specific examples. Plastic storage bags for the freezer. I fucking buy those to keep things I make fresh. I buy the same 'medium' bags, and the cost varies, but I have boxes containing 50, 42 or 38 bags of the same size - depending on when I bought them.
You can even go to the display in the grocery store and see! A box of 38 may cost $7, but 3 boxes of 50 shrink wrapped together in a 'bulk pack' costs $12. How the fuck to they price things like that?
