It's easy to get excited about all of the low-priced goods at a dollar store, but you should shop with purpose in order to avoid impulse buys. With that said, party supplies are some of the best things you can purchase at a dollar store. They're reusable and cost much less than they do at big party store chains.
Drawing paper and notebook paper are two more great buys, and cleaning supplies are usually made of the same ingredients as higher-priced products, so you're good to go with those, too.
Keep these tips in mind the next time you hit your local 99-cent store and you'll be cashing in on savings that count.
