Here's a fresh example. Three weeks ago I joined the Doubleday Book Club. In joining I bought five books for $2.94 each (20 cents plus $2.74 shipping).
One of the books I bought was Star Island by Carl Hiaasen, which was #6 that week on the NY Times best seller list.
Inkmesh says that its lowest eBook price is $9.99 at five stores.

Now I understand that book clubs offer low prices. But if you are so concerned about maintaining the integrity of the MSRP of a new book, why do you let the book clubs have it in the first place?
