Walmart, Kmart, Amazon...almost everyone has them on sale now. Picked up Prime for 30 & Starscream for 20 at Walmart. The Prime deal is a steal since it's larger than the Sentinel Prime set that's also $30 now. Not sure if Kre-O is dead yet , it seems they're selling well with these new prices. It's also a good deal for Lego fodder. You could bould some cool stuff with Starscream's parts.
