Sure, it's a great way to get real, natural food at a decent price. Personally I'm a major fan of Middle Eastern cuisine but these days we are blessed with such abundance and diversity you can get just about any kind of food imported from the remotest corners of the Earth.

Also, I very much agree with your observations re: long term storage foods. There are usually plenty of choices at various ethnic markets and they tend to be much better (tastier as well as healthier) than canned or dehydrated rations.
