Look what came in the mail yesterday! A sample of Honey Nut Cheerios (from signing up from their website) which probably has a coupon inside the box, a coupon for a free bag of Skittles from entering a code from a Skittles bag on their website, and a coupon from CVS for a free Gatorade Fit product when you buy two others. So entering codes online and signing up for samples and store rewards programs definetely rewards you. I recommend signing up for rewards programs from stores you frequently shop at and for signing up for samples from legitimate companies. Not only do you get free stuff (yay free stuff!) but often samples come with money saving coupons, so double win.
