Default Receive $5.00 off Sprint bill for taking a survey!

I got a card in the mail 2day from sprint asking me to take a survey. It took alittle longer than specified but i guess its definatly worth it. upon completing it asks for phone # to credit account and email address to send also for details to complete up to 3 surveys per year. Goes as the following word for word ...
