Okay, with 72 locations in 11 states, Half Price Books is undoubtedly a chain. But with such a great selection of ridiculously underpriced books, it's worthy of our esteem. Where else could you find a like-new trade paperback of All the President's Men for a scant two bucks, just a few months before the 30th anniversary of Watergate? There is a huge collection of paperbacks, all priced at half-off the cover (hence the name), which makes this a great store to troll for beach reading. It's also a delight for book collectors, who should stop in once a week to peruse elusive, out-of-print gems.
