Book Buy Back is always held during finals week at the end of every semester and we buy books during this time frame ONLY. There is no guarantee of a buy back; however Pioneer Mercantile strives to buy back as many textbooks as possible. Once quantity requirements have been met, any books with national demand may be bought from one of the other 3 companies we partner with. Nursing books are not eligible for book buy back. Price quotes are based on “new” books, “used” books will be less. Pioneer Mercantile reserves the right to deny a buy back based upon the condition of the book.
