5. Preserved Goods
Usually, the dollar store has great deals on pickles, olives, salsa, and other bottled, tinned, or packaged, long-lasting items.
Just make sure to check the expiration date, although most of these items usually last a long time.
Some dollar stores even carry perishables such as produce, dairy, and meat products.
Be aware that many of these kinds of goods will be close to their expiration dates, but if you plan to eat something on the day of purchase then go for it!
