Not sure if this is noteworthy or not, but the packages for the "Great Kre-O Giveaway" are starting to arrive. Mine arrived yesterday and it came with the BotCon exclusive version of the Optimus Prime Kreon, a gray T-shirt with Movie Optimus Prime's truck mode grill on it, and a $5 off coupon for all DOTM toys.
I think it says on the coupon that they can not be used in conjunction with any other ones, so you'll have to make two separate purchases to get the full $10 off.
