Hey, you are the seller and you have the right to 
choose how you can and want to send things.  I've 
paid some outrageous shipping fees myself for 
both domestic and international items.  If I 
really wanted the item, then I had to accept what 
the seller was charging for shipping. (And 
frankly, I'm happier with a more expensive option 
for things coming from Canada - my only transit 
losses were items from there - not from Japan, 
Malaysia or Hong Kong, but Canada!  Go figure.)

In my own auctions where things are going 
overseas, I'll offer mostly Global Priority where 
possible, but I feel bad for people who have 
bought $2-worth of cels and are paying $10+ for 
shipping!

That person should try buying something from a 
different category, say, computers or personal 
electronics, if he/she wants to stroke over the 
non-negotiable shipping charges!
