For the sheer quantity of books it would get a high rating ... but for quality and books you'd want to buy ... a lower rating. I asked and they said the books are from "a used bookstore going out of business in the Midwest" ... the books seem very old and not "interesting" reading. It seemed like it was the remainder of books left over after a used bookstore sold all the good books ... and the remaining books were taken to the goodwill but instead were brought to Arizona. No offense but the books are not good and high priced. Price of books at 1/3 of cover price would be about $7 to $10. Their trade policy is not even very good... 50c or $1 per book trade. It's also very dark on the lower level. Try Changing Hands books instead ...
