I got this check from mysurvey.com (uses a point system for every credit or reward on survey completion)which is a great site that offers both cash and merchandise rewards. The cash can be redeemed at 1000 points is to $10.00. This check was a trail redemption at that time to see if it's legitimate and really pays. I haven't tried redeeming any merchandise because I am still stacking my points for one of the highest rewards. Once I accumulate the points I need, then that will be the time that I will take advantage of the merchandise. As for research samples... they also give you a chance once you qualify that certain study.
