Does this freakin' thing work?

OK SO MY HUSBAND DID THIS ONLINE SURVEY, AND GOT A $50 AMERICAN EXPRESS GIFT CARD, WHICH WAS NICE, THE ONLY THING IS WE CANT FIND ANYPLACE THAT ACCEPTS IT! IT HAS FUNDS WE EVEN CALLED THEIR CUSTOMER SERVICE AND THEY SAY IT LEGITAMITE. WE LIVE IN THE DALLAS, TX AREA, SO MY QUESTION FOR YOU ALL IS, DO U KNOW OF ANY STORES THAT WILL ACCEPT THIS, OR DID WE REALLY JUST WIN FOR LOSING WITH THIS ONE?
