Shipping - Media mail for actual weight is all that will be charged. If you purchase one or two books they will be shipped in a bubble mailer with cardboard support. More will be shipped in a box carefully packaged. Shipping is combined on multiple purchases.
Returns - I have tried to describe the books in detail and a picture of each is shown. I am not an expert grader of paperback books and due to the modest value have not spent a lot of time with each issue. An error or two may be made. If you are unhappy with your books for any reason return them for a full refund.
