I'm a fan of Thrifty Joe's. This store has a good selection of the books I tend to like: nature essays, history, historical fiction and regional books. The selection changes literally everyday depending on what people happen to bring in. Also the prices are great. Some new books area available too and they always seem to have a great number of copies of all those book that are required reading in the local high schools.
I do wish, however, the ambiance of this store was kicked up a bit. There is nowhere comfortable to sit and browse through your pile of picks to decide what to buy. There is no coffee available. There are never any book signings by local authors or other events to bring people into the store. The store is neat and organized though. I wish they would take a page from the Changing Hands playbook and get it in gear to drive more people to the store to both buy and sell.
The book selling process is easy and simple. Bring your books, dvds and games in on a day the book buyers are there (almost everyday) and you just wait while they sort through what they will take and what is going home with you (or to the Goodwill across the street). The book buyers are careful and they seem to select wisely. I have found some real treasures in these stacks over the years.
