How can I go about doing this? I've found some parts I need to buy on Yahoo Auctions (worth about £350 over here (Toyota prices) but it's £5 worth of scrap in Japan )

I've seen this website but it's not massively clear how it works. Has anyone on here used it?

Are there any Japanese speaking people on here that can help talking to the seller to find out postage costs, etc?

Are there any importers who'd be willing to bring in low value parts and deal through Yahoo Auctions on my behalf?
