The only country I've had issues with for buying or selling is Canada. I always insist my funds in US dollars through paypal, the buyer paying the extra. I keep a stack of customs forms in my office and my PO is very knowledgable as to foreign shipping, though it is a very small town in the middle of no-where. I have also refunded over charges for shipping if I quoted to high. I actually enjoy doing business around the world and have shipped to moscow, Poland, Australia, etc. There are several folkes in the UK and Norway that have recieved items from me for free, or just sent postage after recieving the item.
