At my Kroger, almost half the times I try to compare unit price bergen two products, the units are different (e.g. $/oz or $/lb or $/g). And these are always products right next to each other on the shelf.

I noticed that at Tesco in the UK as well (but that was ten years ago), they also mixed GBP/piece into the mix.
