At AT&T, sign up for a select AT&T U-verse Broadband / TV / phone package and receive up to $250 in AT&T Reward Prepaid Cards for free. (Reward amounts start at $100 and a "U-family" U-Verse TV package or greater is required to begin receiving rewards.) Although not as strong as our June mention, it's still one of the best reward card offers we've seen from AT&T. (Be sure to select "AT&T Promotion Cards" from the drop down menu when choosing your services.) Click here for complete details on reward requirements.

Note: Although plans start at $19/month (for TV only), the cheapest eligible for a prepaid card appears to be the U-Family TV service — which includes a $100 prepaid card — for around $29/month. It includes up to 130 TV channels and one DVR. (Plan prices vary by location.)
