@myuu: 8900 yen is nearly 97 dollars (according to xe.com) and that is the price the site you posted lists. Shipment not included.
Now, from what I see in that ebay listing the price in Singapore dollars....
According to XE.come again, 100 Singapore Dollars equals around 72 US Dollars.
Sure, the plushies are not exactly cheap but unfortunately those are the prices they are usually being sold at nowadays...especially in non Japanese sites.
Though, if I remember correctly from the lsat time i felt masochistic enough to browse the japanese yahoo auctions for X merchandise.....the prices on that site weren't that low either.
In short: Sucks, but that item isn't anymore overpriced than hide plushies generally are nowadays...>_<;;;
