MCR awards 10 bonus points for codes from PowerAde Play caps (one bonus per account during May). It's their new product. The problem with regular PowerAde caps is that sometimes they post to the account as if the code was from Minute Maid, which means no bonus.
I have no idea if they are play... do the caps look different? If so, I'll tell you. Otherwise I have no way of knowing, because I don't have the bottles anymore.
just an fyi regular powerade caps can count towards the 10 bonus points. i just did it. i entered in a regular cap and when it asks you when drink you got it from it gives you the option to selet the powerade or powerade play. i selected powerade play and it instantly gave me the 10 bonus points
