Buy the Book, Renton's downtown used book store had a good selection of genre books -- science fiction, mystery, romance, mainstream, plus many text books, resources, art books and the like. They are a small shop with prices that I saw at half-price new or less and do have an exchange program for your used books. They did have some new books in stock. Parking is available on the street in front of the store or in the area or at the big public parking garage. Staff was very friendly and not in your face -- they let you browse until ready to buy.
