I think this is the only store I've ever been in where you can honestly buy an item for 10ยข. This place allows me to buy expensive foods that by rights I shouldn't really be able to afford. Things like good cheeses, greek yogurt, sundried tomatoes, and sesame oil, all of which I have bought from ADF.
Yes, you have to look at what you're buying. They do have products past their expiration dates, so if that bothers you, don't buy those products. No, you can't really come in with a shopping list and expect to get everything on it. What they have in stock depends on what they can get, so it changes week to week. Also, I wouldn't recommend buying produce here: the prices aren't any lower than on sale at your regular grocery store and the quality is worse.
