Here are three ways that you can boost your Pampers Gifts To Grow rewards points balance by a total of 45 points! Firstly, head over to your account where you can sign in, and enter the code CM8HFD7EW38BU15 for 15 points. I am unsure about the expiry on this one, but I can confirm it worked for me just now so it is still active.
While signed in to your account, come back to this page, and click this link. You should be taken back to the Pampers site and receive the message that 20 points have been added to your account. You can then come back and click this link, and you should receive the message that another 10 points have been added to your account. I did have to log in and out again to get the links to work and the points to add, so give that a try if the points are not added right away.
