I just picked up Avengers Assemble HC volumes 1-5 off of eBay and the seller is trying to charge me $165-$260 US for postage to Australia from Canada. 

I know there is a difference between there and the US for prices, but if it had come from My Comic Shop or TOW the cost wouldn't be a cent over $80 US. 

Any Canadians out there who can give me a good idea of what I actually should be getting charged???
