The Coins are like all "voucher" -Deals both a marketing and an increase in profit tool. Surprising that it comes only now. Either win Amazon because the customers are more likely causes to Buy, as if you have to pay money or Amazon gaining the advance, which they then invest in the financial markets until a product is purchased, against that then the payment would have to be offset. Therefore, the discount is much too low = the Coins overpriced. If the coins would be traded real, a la bitcoin, a real value would quickly identify.
