I edited another possibility into my comment as you were replying. You wrote here that you asked 'how much it would cost shipped 2 Ireland.' If used numbers in place of words in writing to him, just as here, he might've thought you were asking on the postage for 2 figures to Ireland, which if so would mean he was quoting postage at $60 each ($400 + $120). Maybe that's it?
Well now that you mention that, i searched my sent folder to find my original message i sent "how much shipped 2 Ireland? thanks." ..so ya it could be a misunderstanding, but this is no over reaction as there are dealers like this out there who are just out to screw people over,and we should all be aware of them ..so i wasn't in the wrong in how i reacted to his price.
2 put an end to this ..can someone else from Ireland or the uk who has a youtube account ask for a price on the figure(being very clear its just the one figure)it will be interesting to see what price he gives, but the message i sent to him since may have had an effect lol.
