Often different thrift stores have a reputation for having more of certain kinds of items (clothes vs. electronics, etc.). Whole Foods and the like have a number of wonderful products, but simply aren't affordable for people on a budget. Search for any low-income stores in your city or town (i.e. Aldi) and shop there.
