Today's side deal gets you $10 worth of used books and media at the The Book Cellar, located in the basement of the San Antonio Public Library's Central Library. The Book Cellar is open from 11 a.m. to 3 p.m. every day and stays open until 7 p.m. on Thursdays.

Operated by the volunteer-based nonprofit Friends of the San Antonio Public Library, The Book Cellar houses an extensive collection of used fiction, nonfiction, reference books, magazines, and media for purchase at extremely low prices, usually $0.50 to $1. The wares themselves have been donated by the library, and proceeds from the sales support library programs and activities such as the Summer Reading program, satisfying patrons' philanthropic side while indulging their tendencies toward bibliomania.

The selection changes daily, and includes some Spanish and foreign-language selections. Bluestockings and bookworms can replenish their home libraries with a plentitude of paperbacks ($0.25–$0.50) and hardbacks ($1), as well as antique and premium books, most of which are available for less than $5. Children's books and romance novels run slightly cheaper ($0.25–$0.50), and magazines round out the best deals at $0.10 each, or 12 for $1. Media hounds needn't worry about being left in a lurch—the Cellar also stocks LPs ($0.25 or $1 sets) and videos ($1) for vintage audio-visualizing.
