thanks. its kinda like with the coke codes and other codes, you have to have an account set up on HUGGIES.com and you enter the codes in to earn points on their site to use for any of the various rewards they have on there. as far as what kind of rewards they have i don't really know for sure. i tried doing it in the past but like with all the others it was just too much for me to try to keep up with. :)
