Yes, some asking prices were US$500, but selling price at auction and BIN is between US$275-400.
One boxset sold as BIN for US$455, but then, there was another auction that went for the same amount that had all the at-show toys with it.
Oddly enough, two bagged sets sold for more as BIN, than two boxed sets that sold at auction.
Kinda shows that if you are desperate and can't wait for an auction, or can't bid on an auction in America, people are willing to pay $100 more for a BIN.
