Japanese brand Innocent World is having a winter sale right now, with 30-50% off JSKs, OPs, skirts and more. Fans of Classic and Sweet styles can find some great deals, and there are even a couple of Gothic-friendly items. (Shopping service needed if you live overseas.)
Also, if you happen to be in Japan in March, IW has just announced they'll be having a 2-year anniversary party at their Nagoya store on Sunday, March 15th. They're still working on the details and will announce them once they're settled.
