I went to Pegasus & Pendragon Books & Music, which is a local bookstore that has two other locations in the East Bay. This bookstore is much like Barnes & Noble and Borders in that it's great if you're not looking for something specific and old (say something published more than 15 years ago and isn't a bestseller). Otherwise, the prices are hard to beat. You can purchase a number of bestselling books at a fraction (around 1/3) of the cover price.
