GameStop has teamed up with E-Rewards to give people special GameStop gift cards for their participation in surveys. The email I received says the following:
By answering online surveys that match your age and interests you can earn gift cards. The ad does not say what amounts the gift cards are in or how many surveys you have to do before earning a gift card.
After signing up, you will be directed to answer a survey of questions. It’s rather long so make sure you have time to do it. Also look for small checkboxes that allow the company to share your information. There are plenty of those and you want to make sure you uncheck them before you end up receiving a ton of spam. Not sure if this is also an indication to their service, but the surveys that are available for me are from 2007.
