Yeah, MP Starscream sold out in less than a week! Real glad I grabbed that toy on sight! Also $150 for MP Optimus Prime/w trailer and roller is relatively cheap considering that:
+ MP Grimlock sold here for $150
+ The previous MP Convoy w/ trailer sold here for $250(ish?)

MP Optimus Prime may sell like hot cakes, or it may shelf warm -- time will tell. But I'm not going to chance it. <shrugs>
