Franco62/Shutterstock Many Costco shoppers might guess that stocking up on toilet paper is one of the best ways to save money. In fact, you might get a much better deal at your local supermarket or Target. A 45-count package of Cottonelle Ultra sells at Costco for around $28.99, while Reader’s Digest found a 36-count package of Cottonelle Ultra at Target for $16.99. Per roll, that’s a 17-cent savings at Target. Plus, you won’t have to reorganize your entire pantry to accommodate your loot. Thinking of doing it anyway?
