Um...did't you get the news?
"Due to the difficulty of finding vintage Scout Troopers, among others, at retail, we are relaxing the criteria that consumers send in one of each of the five vintage figures to complete the offer for the George Lucas in Stormtrooper disguise mail-in figure. Effective immediately, consumers may send in five stickers from ANY mix of the five eligible figures. Certificates completed as such will be honored. Thanks for spreading the word to the Star Wars collecting community!"
