Once payment is made, I must ship the item within three days. I cannot hold and combine outside of those parameters. I will do my best to combine the orders within that timeframe. I can ONLY SHIP TO THE ADDRESS PROVIDED ON CATAWIKI. If you have two addresses, please manage your address before buying. If your book is returned because you did not pick it up, we expect you to pay for the return postage. We put your phone in the package, so there should be only a rare reason it cannot be delivered. All this aside, I very much appreciate selling you books from my collection and hope they find a good home. Page coutn is approx
