Costco and TJs both sell items like meat by weight, they're just pre-labeled so they can be scanned rather than weighed at the register. Things like produce that might be weighed elsewhere are sold by each or container though.
And regular grocery stores like Kroger do much the same thing. Aside from picking out individual produce items, and even then a lot of times it is per-item pricing. Nearly all of the by-weight stuff is pre-labeled
