I would like to get at least 5 credits per order, so I am offering up to 15 books for 5 credits.  If I get multiple offers, I may have to postpone the send date a little.  The offer is good for both hardcover and paperback.  I will be posting more books, so if you don't see something you like, be sure to check back later.  Also, let me know if there is something you are looking for.  I may have it, as I have lots of books I haven't gotten around to posting yet, and I also have lots of unpostables I haven't listed.
