We live in the area and frequent this business regularly. It's a great place to pick up bread, bagels, or English muffins. You'll pay a dollar for the same items that run $3.99+ at supermarkets.
You won't always find the same products here week after week. Some items are always available, but pizza crusts and specialty items come less frequently.
Sometime there is a lady there who is crabby, but I think it adds to the experience. Did you ever ask her why she's having a bad day? It could be because she only gets paid until store closing. After 6pm she isn't getting paid for clean-up, etc. it's not an excuse, but sometimes people aren't happy for a reason.
