I was referred to this site from Survey Junkie, my VISA card DOES work but the process of signing up for this site was ABSOLUTELY horrendous. For some reason it wouldn't let me use any of my emails even though I've never signed up before, and when I finally entered an email that wasn't "invalid" it claimed my emails didn't match for some reason. It took me 10 minutes to get one to work, but since the card was legitimate I think 3 stars will be fair.
