I buy books from Avenue often, their prices are honestly the lowest I can find anywhere. The staff is also very helpful if you have a question. You can sell books to them online for cash too. Moola4books.com buys nearly of my textbooks though the mail and returns a check to me within a couple of weeks. They make it very easy to sell my books. Recommended all around, A+!
I haven't sold books to them, but I have purchased many. The selection is good, the staff is helpful and willing to look for books in stock if you call them.
This store is excellent for children that need extended sizes. We always find jeans for my daughters.
