I still get surveys quite often, most of them I don't qualify for, but whatever, I'll take the $.25-.50 for each of those no problem. I never signed up through Gamestop, though. I signed up on the actual eRewards site a few years ago. I've been grandfathered in for a long time on the $25 Gamestop giftcards for $50 eRewards credits, but in Q2 this year they raised my price to $60, which I'm okay with for now, but if they raise it to $75 I'll just stop doing surveys. I won't close my account but I'll just continue to add a few cents here and there from not qualifying for surveys. Sometimes you do get lucky and they throw you a super easy survey that's worth $10+ eRewards credits. Those ones are usually for surveys about TV commercials, in my experience.
Remember to fill out all the optional information that you are comfortable with giving out on your profile to increase your chances of getting surveys. Those profile questions make a big difference in how many surveys you get.
