$100+shipping for a jewel case only game? I next to never buy PC games without their box. Plus, I import items from the US, UK, HK, and everywhere else all the time, and shipping really isn't very much. A CD from Japan would only be a couple bucks to ship to North America.
BTW, this really isn't the place to advertise your eBay listings, unless someone else does it for you, just pointing out a neat item they found or something, heh.
