What Amazon has been doing for the past couple of weeks is amazing. So to add a little more Thunder to their story, we’ll let you know that the Motorola Atrix 4G on AT&T is now $150 cheaper, and selling for $49.99. This deal is available at the Amazon’s Wireless store. With no formal announcement yet, it’s hard to conclude how long this deal will last. Knowing that, it wouldn’t be a bad idea to lock this down right now. As expected, this pricing comes with a two-year contract on AT&T. So for all the future Atrixters, go and save yourself some money.
