I knew some folks that used to own a "dented can" grocery store named Dirt Cheap Grocery. They would find all sorts of deals on entire lots of nearly expired canned and frozen goods and what ever various other things they could find through their various connections. There would always be something different, and they would have some pretty incredible deals sometimes. I remember buying an entire case of frozen hash brown patties for $5. There were six 5 lb bags in there. we split it up with my wife's sisters families. Another time they had those Michelina's frozen pasta dishes that had just expired for 10 for $1. My favorite deodorant scent had been recently discontinued and they just so happened to get a hold of a big display bin full of hundreds of them and sold them for $1 a piece. It took me several years before I finally ran out...
There's one fairly local here. They carry non-perishables, and their stock is definitely better than the dollar store. They used to be called "Freight Liquidators."
Taco Bell, but not from like an actual Taco Bell, from one of those food court “express” ones with the limited menu that’s always out of something like sour cream.
The local ones have a freezer with ice cream novelties, much as you'd see in a convenience mar. I assume there's a business synergy of having kids who have to look through 500 slightly differently sized used "size 12 jeans" to find the ones that fit, and buying their compliance with desserts.
