You can SEARCH my store by TITLE or AUTHOR using the box to the left. To receive the Shipping Discount you will need to wait to make payment until all your purchases are complete. Click the Buy It Now on each book but don't pay until you are completely done shopping. I HAVE MY OWN SYSTEM OF RATING THE BOOKS THAT I SELL, PLEASE USE THAT ONE AND NOT EBAYS. If you buy more than one book, please request a total from me, DO NOT USE CHECKOUT, please do not pay until after I send you an invoice for the combined purchase, otherwise, I will not be able to give you the shipping discount. To qualify for the discount, you must pay for all of your books in one payment, on one invoice. If you should have any problems, please email me. I will be happy to combine your purchases within 3 days of the first purchase, just let me know that you are not done shopping. All payments need to be received within 7 days of purchase.
