The coupon codes were completely distributed in under 10 minutes last time, so today is your last chance to save $150 on an off-contract Moto X. The website just went live with the promotion a moment ago. Don't waste time – gogogo.
To sign up, just enter your email and begin the waiting game. In a few hours, Motorola will email you with a single-use coupon code to get $150 off a Moto X through Moto Maker. The developer edition phones aren't included, though. You'll pay $349 plus tax and shipping for the 16GB Moto X on AT&T, T-Mobile, Sprint, or Verizon. The code will only be valid for one week.
The 30% off accessories coupon code 'THANKS' is still available too. It's good on headphones, cases, and other goodies. Best of luck to you this time!
