Unfriendly staff.  Have been in twice, both times I left unhappy.  This is supposed to be a used bok store, but the only want you to trade in books you bought new.  They refused to accept two books I purchased from them.  There are so many policies regarding what they will take and then more policies how you can use your credits.  I wont be back!!!  One star only because i can't leave \"0\" which is really what they deserve.
