I know I can't afford them either over here. Way too expensive even for a tron fanatic. I used to collect pins myself from different things like car show, Howrod shows and even from Science fiction shows. The most that I have ever paid for a pin was about $10-15 $20 maximum and that depended on what it was colourde in or not. All in Canadian prics as well.
Last time I remember when they were getting ready to bring out the game Tron 2.0 they had a set of new pins for that. And it was about 40-50 american. If they realized even if they were a limited edition. They should have made it still realonable to buy without hurting the pocket. for a nice set like that.
