I never thought I’d buy groceries on Amazon, but I have now, and paid double what I would have at the store. Wal-Mart, in my experience, carries a thin inventory running out of items frequently. The effect of that is that I carry a two or three week’s supply to avoid getting caught short. After three weeks of them being out of canned Ranch Style Beans with Jalapenos and Publix not carrying the item at all, I was surprised to see the beans available at Amazon, although the price was double. I bought all Amazon had (four six-packs of cans). Wal-Mart still hasn’t restocked.
Same type of situation for my cat food but Amazon was actually cheaper.
