But on the other hand is the 50% refund more incentive to actually purchase a book at the airport instead of passing on by the store? And since rebate participation is usually less than 20% or less, is much really lost? Is this any different than selling the book to a second hand bookstore who then re-sells it? Or donating it to a thrift store? What about selling it at a garage sale?

Interesting to think about. Not being an author I hadn't thought about it that way.
