Here is what it says on the CVS site:
We’ve created the CVS Advisor panel to gather your input about CVS stores, products and services. In addition we’d like to hear your suggestions for how we can improve CVS. Your guidance is especially valuable as we strive to make your shopping experiences at CVS the best they can be.
Throughout the year, we will send you invitations to participate in online surveys about CVS products and services. If you choose to participate in our surveys, we will thank you for your time by providing you with a self-printable CVS ExtraBucks coupon immediately after completing our survey. Becoming a member of ExtraCare and the CVS Advisor Panel is FREE. (Note: Advisor Members are eligible to receive CVS ExtraBucks coupons for surveys that are completed after the initial membership survey.)
