Not just the price. Have it tell you any one of a number of information types that you personally value. Such as if that item has any ingredients that you have blacklisted (or your doctor has). Have it show you a "Pollan-score" for the item or reviews of it by experts and/or friends. Have it tell you a guess at what ratio of the price will go to corporations that you do and don't like the politics of. Did it get shipped on a boat that has a carbon-emission rating that is higher than you like? Is there another brand sold at this store that more closely matches your preferences, and if so what does their packaging look like?
