I am also in love with the blue fonce, but unfortunately I was not even into Chanel when it came out (I think sometime early last year). It is seasonal. It will most likely get re-released again, but who knows when that will be? I know it won't be released for spring/summer of 2008. Perhaps late next year or the year after?
Trust me, I had my SA try to hunt one down and they're completely gone. The only way you'd find one is to get lucky on eBay or a consignment shop.
