Their is a large thread about it over at fatwallet . If you do not trust free things then really look through their free stuff forums . I recieve about 3-4 items a week just becasue I sighn up for everything .
There is a big difference between this survey and a free ipod site .
What happens is shutterfly commisions a survey company to do market research for them becasue they do not have an in house agency . The survey company wil honor the deal on about 1/3 of the applicants . This is becasue the only way to get people to really take surveys online is to give them something (ussually gift cards ) and for people to not call it a scam they need at least a few voices popping up saying hey I recieved my product from them . So yeah you are not garunteed the free card but for the 2 minutes it takes you I would say it is worth a shot .
And if you dont allready have a spam email account you should get one . Not only for deals like this , but for all your purchases online . Even ebay will send a lot of annoying ad's and it is nice to consolodate all the garbage into one account .
Just my 2 cents to all you skeptical people out there .
