2. Books

The selection of books at warehouse stores is impressive, but you might find better options elsewhere. Shop for your favorite titles at a used bookstore or Amazon.com for the best book deals. Your local library may also have a “Fill-A-Bag Sale,” where you pay a single price for an entire book of bags. With summer coming up, be sure to hit yard sales too, where you can find books for pennies on the dollar.
