Could not find this here on on the wiki:
How would you normally tag a shop that sells food items that are nearing expiry or past their best before date, at heavily discounted prices?
These shops have risen in popularity and we have a few of them around now, but I can’t really see any better tags than the general shop=convenience or shop=supermarket.
There’s the shop=variety_store that has the title as “Discount Store” but I understand that that is more for cheap clothing and trinkets.
Normal commercial operation. Definitely not a charity or a food bank. It’s like an outlet store but for food. That said, doesn’t look like there are any common tags for tagging a non-food outlet store anyway.
In the US we commonly call them Bent ‘n’ Dents or grocery salvage or outlet. There’s a brand of a chain of them in Wikidata. They’re all just tagged supermarket, I think.
