Ok. I may have this figured out. You pay the full price for the PAPER book and then you get a special gift card good only for the purchase of the e-book version (which is not transferable and sellable, so would not be prone to abuse or lower the market rate of the printed book)
That is how Amazon can increase e-book sales and allow people to keep a hard copy and enjoy the portable and light weight convenience of the e-book.
Like I said, this should not decease profits, but increase them, because it would appealing to customers who would otherwise buy only the paper OR the e-book, not both, since paying full price for the same book twice is very unappealing.
