Shipping to Canada suuuuuuuuuuucks. If you guys would simply have fixed rates it would be fine, but typically (for the outlying areas) it's "Show up at the door and we'll make you guess how much you owe."
I hate how difficult your country makes shipping - and it's all duty-based. FedEx, etc have their stuff together. They just can't predict what mood the Canadians will be in when the items arrive.
We've seen tons of manufacturers label boxes of electronics as valued at $5 and classify them as something else entirely just to avoid the ridiculous duties, etc.
