[HELP] Amazon.co.jp

Hi!
I'd like to have some help/feedback about amazon.co.jp, if any of you already ordered from them
1 - Do they ship to Europe?
2 - Shipping fees? (how much per order/per things you order).
3 - Have you been satisfied by them?
4 - Mean of payment? (Paypal? Credit card?....)
I'm not sure I translated well their pages, so I'd rather ask before ordering badly XD

So far, I order via yesasia (no shipping fees) but they are quite slow ~~

Thank you for your help!
