Better if you could also earn coins through purchases
on May 13, 2013
I buy stuff on Amazon all the time so it would be great if with every purchase you could also earn coins. A coin for every $1 or something. That would probably give people incentive to buy stuff through Amazon if they knew that they could earn points towards free Kindle content.
