Bookworms and collectors throughout the Valley have been known to stow away cash for this annual sale months in advance, and with good reason. For one glorious weekend in February, the Volunteer Nonprofit Service Association fills a warehouse at the Arizona State Fairgrounds with hundreds of thousands of donated books, from museum catalogs and ancient tomes to comics, paperbacks, religious texts, and even volumes in foreign languages. Vinyl records, CDs, and DVDs are also available for perusing. Best of all? A massive chunk of the selection can be had for less than $5, with many of those going for just a buck. Bibliophiles from all over gather in the chilly predawn weather to make sure they get into the sale early enough to get the best selection. Make sure you know how you're going to bring all those books home, though — you're likely to fill at least one shopping cart by the time you're finished.
