Rite-Aid $3 Off $15 Purchase Coupon - Multiple Opportunities

Make sure you are checking the bottom of your Rite-Aid receipts for the opportunity to receive a coupon for $3 off your next purchase of $15 or more at Rite-Aid by taking a short survey on-line.  I have received 4 receipts in 1 week already with this survey opportunity on them.  I have already cashed in on 3 of the coupons.
