There aren't any Pampers products worth 50 points (even). Those only codes worth 50 points are: WELCOME2PAMPERS JOINNOW4REWARDS giftstogrow4mom 2BEGINEARNING50 ...and those are promo codes. Everyone can use them once.
What product is your code from? You're confusing people by saying it's worth 50 points. Nothing on the points matrix is worth 50 points... that's all!
