I just entered the promotion code h24870p43h8037 for the Cheerios Helping Hearts promotion that was inside the box of Cheerios that I had just finished. Then I figured that while I was at it I'd enter the promotion that was in the box I hadn't opened yet. Imagine my surprise when I opened the box flap and found the same promotion code h24870p43h8037.
At first I thought it was a printing mistake, but when I entered the code again. The site said that it was accepted and that a dollar was being donated. Hopefully that is what actually happened.
I wonder if its true for all the codes?
I was also happily surprised that no name and address information was required to activate the code.
