This is the best part. The prices are lower than you will find anywhere else. The bargains are amazing. You and the kids can walk out of a sale with an armload of books for less than you'd pay for one book at a traditional bookstore. It depends on the sale.
Most sales have several thousand books.
Again depending on the sale, about half to three-quarters are hardcover and the rest are paperback. Many of the larger sales have an enormous assortment of books, and they are usually sorted at least as well as you would find in a traditional bookstore. And speaking of bookstores, some groups run used bookstores, which rival for-profit businesses in professionalism and selection. The stores are open during regularly posted hours either year-round or seasonally. Like any other bookstore, they afford you the opportunity to browse at your leisure.
