Have not been doing E-rewards as often lately, but just had one recently that paid off big! It was a fairly short survey about restaurants and at the end asked if I'd be interested in an in-person focus group, to which I said yes. It actually happened - a consulting group contacted me and I just made $150 cash yesterday for an hour of my time. Funny thing was, there was only one other person in the "group" - she mentioned she didn't even remember how she got picked for it. I said "Oh, I do a lot of online surveys so I think it was from that" and she replied "Yes I do E-rewards, so it must have been that!".
