I go to the store pretty often - to get camping supplies (they have a variety of fake meats in cans) and pick up some food for home. The store has frozen section with burger/nuggets/crabs/etc. imitations, canned food, vegan sour cream, vegenaise, breads, snacks, supplements, and much more. Not everything is vegan, so read the ingredients. If you buy in bulk, use their sale periods.
Cons: not everything is vegan
