I've just had an e-mail from the bobble head dude on e bay saying he needs another $25 for postage, which okay, they're heavy I know but he was the one that wrote down the international postage not me.

if he indicated on the eBay listing what shipping would be, I don't think he can raise it later on. if he told you in an e-mail, he still might need to stick with that stated amount. I'm not positive what eBay's rules on that are, but you might want to check this - cause an extra $25 is an awful lot to increase it!
