Sometimes American sellers forget that 'civilisation' extends beyond their borders so email the seller and tell them that you can pay in US dollars via PayPal and ask them if they'll consider selling to you and you might just be able to convince them...
BTW - you may have noticed a little flurry of "Welcome to the Forum" messages - it seems strange and unnecessary at first but you'll get used to it!
