There are 10 free Pampers Gifts to Grow points available thanks to code 4WJDHKU4RPP6PT2. Additionally, new members can get 100 free points to kick their account off by going to the last page here. There are 17 pages, so instead of clicking “next” a bunch, click on the 10, then 14, then 17.
Oh, the second link doesn't work in Google Chrome for some reason. I like to imagine the reason why is because Google and Pampers are in some sort of secret blood feud. But it's probably something lame like browser compatibility.
