I have had so many problems with international 
bidders: complaints about shipping costs, 
refusal to pay (or not paying without letting me 
know), misunderstanding on the types of payment 
types accepted (IE When the auction CLEARLY says 
no credit cards by Paypal, why be pissed off 
when you can't send me a credit card payment??), 
not speaking English well enough to conduct 
business, etc. What I finally did was to put a 
disclaimer in my auctions: All international 
users must email me BEFORE bidding for payment 
and shipping terms or I will flat out cancel 
their bid. I really hated to do this because I 
have had MANY more good experiences with 
international bidders than bad experiences, but 
the bad aren't worth the trouble....
Another problem with international users is they 
request that you lie on the customs forms. I 
don't mind sending the item as a "gift" but I am 
not going to fake notes or list the incorrect 
value. I actually had one bidder who wanted me 
to write "$25" value on the customs form but 
insure the item for the actual $200 value!!! 
(Come ooonn!!!) 
I think a lot of the reasoning for the 
misunderstandings about shipping is the 
difference between "Airmail Letter" and "Airmail 
Parcel". The costs can be QUITE different, with 
the letter cost being lower of course.

Just my little babble.
