In Canada we have to pay "brokerage fees" and import taxes (our federal and provincial taxes combined) on the cost of any items, shipped from an international location, over $20.00. Sometimes they get me with it, sometimes they don't. When it comes by UPS they *always* get me. (UPS charges the brokerage fee) and if it comes by mail it's rare that I pay. Guess which way I like to order?? LOL
That's what they are talking about when they state this in the auction. It depends more on your own countries import fees than the sender and they have no control over that but have to deal with the irate buyer who wasn't expecting to pay more for their item.
