Yeah I’ve seen them, my favorite store’s butcher counter has some. The websites have anywhere from 50 to a couple thousand options to chose from.
Actually probably most of them are made from food about to expire. It’s a good way to add a week of storage, and you get to charge more. Win win.
Seems to me selling about to expire food to higher wealth individuals would be a bad business model. If they find out, the store goes out of business.
