Excellent company! I have ordered two different times. I received exactly what I ordered. I have been very pleased with the very reasonable prices, free USA shipping, fairly fast delivery, US Postal Service home delivery, very good shipping packaging to protect the books, and the high quality of the books being sold. The described conditions of the books have been very accurate and well described. The several books that I ordered turned out to be former library books ( as mentioned in their condition ratings), but in excellent condition with no damage aside from library labels and bar codes on them. The selection of books available has been excellent, with hard to find books available in stock, and shipped quickly. I am very pleased with Discoverbooks.com. I will definitely continue to order more books from this company.
