C&R is legitimate. They furnish surveys to SurveySpot and Greenfield (and now I think Lightspeed and GlobalTestMarket), so that's why you don't see anything on them in SurveyPolice's directory or reviews.
I like them because C&R usually sends focus group invites that pay $20.00 or more, so when I see a survey from C&R I get excited. The survey you received from them may have actually been a screener for a focus group hosted by Invoke Solutions, and would have paid $20-$30 had you qualified. What you described is unusual for C&R, and I hope it is not a disturbing new trend.
Speaking of disturbing new trends: my last Invoke invite was a 60 minute online focus group that paid $15.00, instead of the customary $20.00.
Given the good experience I've had with C&R, I would give them another chance the next time you see a survey from them.
I think C&R also furnishes home product tests, does anyone else out there remember that too?
