AT&T has a few campaigns running to increase the sale of cellphones, and now that Christmas is pretty close, the more they sell, the better.

One of those deals is a 2-for-1 offer, also known as buy 1 get 1 for free. The two handsets included in the deal are the following: Samsung Propel, and Pantech Matrix. Every good deal has a negative detail, and in this case it is translated to a mandatory 2-year contract, plus a $35 monthly package.

How does it work:

To take advantage of the offer, customers pay $129.99 for the first device and receive a $50 AT&T promotion card after mail-in rebate, bringing the total cost to $79.99(1). A two-year service agreement and up to a $35 monthly data or messaging package are required. To get one free, customers pay $49.99 and receive a $50 AT&T promotion card after mail-in rebate.
