cedbates, there is another Satisfaction Services thread with a few posts. You'll see it with an April 12 date. There is no discussion there regarding whether shoppers paid or not though.
I've been registered with them for a couple of years, and as always, chose not to pay. Pay to be "recognized" according to their site. I also haven't shopped for them. Is it because they have nothing in my area, or because I didn't pay the $9.99? Couldn't say but it's immaterial to me.
