I utilize multiple book trading sites and requests are sent out on a first come, first serve basis.
Also, any books you request from me are USED. This means they will most likely not be in absolute pristine condition.They will not look like they are fresh from the printing press. There may be shelf wear, even an occasional dogeared page. If you're looking for gift-quality books with which to impress someone, please buy them from a bookselller.
I ship via Media Mail, sometimes using recycled materials..
Some hardcover books do not have their dust jackets. Please ask about the book in question if this is a concern for you.
I mail books on Fridays.
