CVS has a program called the Advisory Panel. You can register for it HERE by filling out a quick online form. It serves as a virtual focus group for CVS and you will possibly be selected to participate in a study. CVS will compensate you for your time in ECBs!
I am a member of this program and I was emailed and asked to participate in a study. CVS then gives you an appointed day and will send you the survey via email. Once you complete the survey( just offering your opinions), you can then print the assigned ECBs.
I did a study comparing drug store circulars and just gave my overall impression of the CVS weekly ad versus a different store. I got the study on the appointed day and it took approximately 10 minutes to complete. I submitted online and was able to print $10 in ECB right after that!
This is a program that is worth the time to register for!
