I can combine items that end within 30 days. EBAY/PAYPAL's fees add up very quickly so its best to pay from one invoice, Thanks. FREE SHIPPING to the Winning Bidder.I will ship anywhere in the United States, Puerto Rico or to any APO for the listed price. Please do not let the auctions go past 30 days, If you do then I cannot combine the older auctions and you will receive a single invoice for each of the books that have gone over the 30 days. A check is great; However for faster shipment PAYPAL IS PREFERRED. Most items arrive in 5 business days! Good luck and thanks for looking.PLEASE NOTE THAT ALL NON PAYING WINNING BIDDERS WILL BE REPORTED. I leave POSITIVE FEEDBACK for all successful transactions!!
