A while back we found out about a cheap way to get the buckets we needed for various dry food storage items (like wheat, oats, and beans). In this way we have been able to provide ourselves with all the buckets we need without paying much money at all. What we do is go to the bakery at Wal-Mart (and this might apply for other grocery stores as well) and ask if they have any empty buckets they need to get rid of. More often than not, they do, and they'll sell them to us for a dollar or two each. Usually we have to clean them free of frosting or "garlic spread" or some other such sticky, processed substance, but once clean and dry, they provide the perfect storage for our dry goods.
Anyone have additional ideas for getting deals on food storage containers?
