The Student Book Store, in addition to every UVA-related accessory and accoutrement (baby-size cheerleader outfits, anyone?) offers a huge selection of textbooks at very competitive pricing. Definitely worth a visit to any student on a budget (is there any other kind) - new or recent editions are priced 15% to 40% below list and related materials such as DVDs or CD-ROMs are often still included (if applicable).
Also featured is a large inventory of dorm and apartment necessities, such as glassware, decor, and novelties. It's practically a UVA department store!
