A Kindle ereader leant against paperbacks

Amazon’s latest Kindle Paperwhite Promotion is a Little Odd

Amazon are running a promotion: buy a Kindle Paperwhite and get a free book. Sounds good, I thought. Perhaps they’ll offer a credit, or that the Kindle might even arrive with the book preloaded. But no. Bizarrely, the book that Amazon are offering to go alongside your shiny new ereader is a hardback.

Isn’t that a bit like giving you a free CD when you buy an iPod?

Talking rot or making sense? I'd like to hear your two cents!
