At AT&T, sign up for a select AT&T U-verse Broadband / TV / phone package and receive up to $200 in AT&T Reward Cards for free. (Reward amounts start at $100, and a "U-family" U-verse TV package or greater is required to begin receiving rewards.) Plus, receive free activation with any U-verse TV online order. Although that's a slight drop from last week's mention, it's still a very strong reward card offer from AT&T. Click here for complete details on reward requirements.
Note: The cheapest eligible plan that qualifies for a Reward Card appears to be the U-family TV service — which includes a $100 Reward Card — for around $29/month with free activation. It includes up to 130 TV channels and one DVR. (Plan prices vary by location.)
