Get $25 Amazon Register credit when you run a transaction by 8/31/15

As the mobile payment wars heat up, the offers get sweeter. For a limited time, Amazon offers you a $25 account credit if you activate and run your first transaction by 8/31/15 on their own Register Card reader which you can purchase from them for $10 with free 2-day shipping. So it’s a net plus of $15. That means you can run up to $1000 in transactions before you pay a fee. Or if you factor in the price of the device, that’s $600 in transactions.
