On Coupons.com you can get 100 free points for signing up for the Pampers to Grow Program. If you are interested in the program and codes to get free points, you can also go here for details.
You don't have to buy Pampers to get the points. I have never done this and don't know how the manufacturers feel about people sharing points without buying anything, but if you are interested you can check it out.
Thanks, Couponing to Disney!
