With its huge selection, its reasonably nice shopping environment and half-decent coffee in the restaurant, this is the place to try before Amazon.com., which, by the way, is a great place to find used books. The last time we hunted for an out-of-print gem, Sebastian Japrisot's One Deadly Summer, even Amazon couldn't deliver. But there it was on one of Half Price's endless shelves, an unread paperback copy for $5.95. On the way to the check-out, we passed on the recycled Blue Oyster Cult albums, but the selection looked pretty deep.
