When a book is purchased from you through Amazon.com or Half.com you will be sent an email notifying you that you have received an order which must be filled. You will have up to 3 business days to prepare the book(s) for shipping and to get them into the mail and on their way to the customer. Your books will be sent at Media Mail rates through the United States Postal Service. This is by far the least expensive way to ship books. The shipping amount that the customer pays you when they order your book will be based on USP Media Mail rates. After you mail off your order yo may be required to send a confirmation email to your customer letting them know that their order has been shipped. This is very easy to do and only involves a couple of keystrokes on your part.
Every now and then a book will get lost in the mail and you may have to send a replacement book to the customer or provide a refund for the order. This is a rare occurrence but can and sometimes does happen. For orders of $20 dollars or more I pay for Post Office delivery confirmation at my own expense. In the event that the book gets lost it can be tracked if it has delivery confirmation. This is only my way of doing things. You may elect not to add delivery confirmation to any of your book orders. If you feel confident that a book will arrive safely without delivery confirmation that will be your call. Because it is your textbook business you can do most things however you want.
