I used to think that those coupon code boxes were for the use of a very privileged few who received a coupon code as a part of a special promotion. Now I know that anyone can get a coupon code because they are widely shared across the internet. My favorite source for coupon codes is RetailMeNot.com. I always check it before making any online purchases. I like how easy it is to use, and that each coupon code comes with a “success rate” and comments.
