Here in the US, while unit pricing is commonly displayed, I frequently find that a store will use a wide variety of units, thereby negating the ability to easily compare items in this way. For the same type of product I may see cost per ounce, cost per pound, cost per each, cost per dozen, etc. for various sizes and brands. It's maddening, insulting, and probably in most cases malicious.

Yeah, this is insane e.g. I've seen cents/fl.oz, dollars/litre, cents/ml, dollars/unit. For the same product. And yes, totally malicious. Fresh Thyme does this. It's ugly.
