Pay in advance, pay fees! Is this covered by Paypal incase something goes wrong?
I don't know about PayPal guarantees, of course that would be a question to ask PayPal, but I've never thought about that. I do know that when I first started using foreign services such as this one (this is the second one I've used), I was also cautious/leery, and as such, I started small, one item, to see if it was successful or not. It was, and I've never had any problems with Masato's service, ever. I don't really like paying commission on top of the bid prices, but his time is worth something, including bidding, receiving, and re-shipping. And until I have a friend living over there willing to do this, it's the only way to get these items from Japanese sellers not willing to ship internationally, which is most of them.
