I usually buy my TF's from either TFSource or BBTS, but RobotKingdom has MP Rodimus for $50 less than the other guys. I know they charge via PayPal and such, but is this a case where they charge me and then I get hit with the difference once they come in? There's nothing about the price being subject to change on the site or anything, but I wanted to check to see if any of you have pre-ordered something on this scale from them in the past. It just seems too good to be true to get it at that price. Any input would be greatly appreciated.
