Now through July 17th, purchase a new Android phone or tablet online from AT&T, and the carrier will reward you. How? The nation's second largest carrier will hand you a $50 Google Play credit. Want a Samsung Galaxy S5? $50 credit. Fancy the HTC One (M8)? $50 credit. Want an Apple iPhone 5s? No $50 credit.
To qualify for the $50 Google Play credit, the phone purchase must include an installment agreement (if you're purchasing the phone using AT&T Next) or a signed two-year contract. A tablet purchase must be accompanied with a signed two-year contract.
The $50 Google Play credit must be redeemed by May 15th, 2015, or else it goes away forever. And if the stock Android fan inside you was thinking that the credit would allow you to take $50 off the price of a Google Play edition handset, guess again. The $50 is not allowed to be applied toward equipment or a subscription.
