U Bookstore is a great place for art supplies. When I was in art school I came here more than any other art store because they had the more obscure supplies (electric/battery-operated erasers!). They also validate for parking no matter what you buy. They have a great selection of books and of course textbooks, and I like to look through their magazines for any new ones that aren't widely distributed yet.
They also ship books for free and wrap them too.
