You can enter them into the Huggies website and will receive points for each code. After you save up enough points, you can trade them in for different items. I don't do the Huggies, because we don't buy them as often, but I know the Pampers rewards have things like the Little Tykes Car, block sets, bath toys, and you can redeem points to be entered into drawings for things like free diapers, wipes, etc.
