I've been a member of SR since end of March, and today I cashed out for $200 in Disney gift cards. Most of that is from shopping at stores through a link on Sunshine, though I also did some offers, and as many surveys (one per day) as I could get.
I think CR ends in dot net, but I could be wrong. I started doing them, but gave it up.
I also do My Points, and have already earned a $25 Marriott gift "cheque", to help pay for our pre-Disney *my high school reunion* trip. Could have gone with the $25 gift card good for Rainforest Cafe, and that would have helped with the Disney part too since they have a Rainforest at DTD, but it "cost" more points than the Marriott cheque.
Do you have any specific questions?
