Even if you don't have little ones in Diapers or training pants. Both Huggies and Pampers has reward programs. And now you don't have to buy their products to get them. Once you collect a certain amount of points you can cash them in for various prizes toys, pictures, gas cards etc. Because some awsome bloggers have already done the work of listing the codes I'm just going to direct you to their sites. There seems to be referral programs which you can get more points for referring. Other than emailing you I don't know how they know how you heard about it. So again, rather than spending the day searching I'm just going to direct you to others. If they benefit great. They are doing an awesome job.
