I don't know if this is a trend but I have either been clicking on old links in emails or logging into the e-rewards site daily since Jan 1 and there has always been a survey to take that I am getting credit for.
I don't ever remember having this many survey competitions so close together. It usually takes me a 3-4 months to get enough to redeem $100 and I already have that just since January 1.
Maybe they have a lot of new clients.
