Is the one in your avatar the black/white?I got both of mine (black/white, white/black) from the Chanel boutique on W 57th St in NYC back around October 2006. You can try there. The style number for the white/black is #A16514X01197. It retails for $140. Hope that helps and that you can find one- it's an awsome bracelet and I get tons of wear out of mine.
