for a time i was able to find the 1 pound cans at petsmart, but not anymore. it's *much* more economical to buy the big 25 pound bag and freeze the rest; i was able to get that at a local feed and seed shop of all places. try one close to you and if they don't carry it, see if they can possibly order it for you. i'd personally be wary of buying it from ebay. it might be just ok, but i'd worry that it might be old/stale. if they have good feedback though it might be fine.
