Walgreens is a drugstore that is popular in the couponing community. They offer a ton of different ways to save money in addition to couponing.
Target is a hugely popular store with really great brands. If you go to a Super Target, they also have groceries and a bigger selection of other items.
JoAnn’s is a craft store similar to Hobby Lobby, only a little smaller. The best thing about JoAnn’s is that it allows coupon stacking on top of their already good prices.
The coolest thing about couponing at Dollar Tree is that everything is already a dollar, which means with a coupon, you are getting the item for LESS than a dollar.
Rite Aid is excellent because it allows you to stack coupons on the same item AND use multiple coupons in one transaction for different items.
