When purchasing goods from the USA, the postage costs are significantly reduced if shipped to a domestic US address instead of a foreign Canadian address. So many Canadians can benefit from having a US mailing address for their cross-border purchases.
As such I strongly recommend dealing with Hagen's of Blaine. Hagen's provides Canadian's with a US mailing address so items can be shipped to Blaine instead of Canada, and the postage savings will be significant. I have been dealing with the lovely ladies at Hagen's for over a decade, and can't say enough of their great and reasonably priced service.
To use their service, you first need to call and register yourself with Hagens. Their tel is 1-360-332-5246. When you register with them they will provide you with explicit instructions on how to have your US purchases shipped to you at their Blaine, WA address. When your item arrives, the fine ladies at Hagen's will call to advise that your item has arrived and is awaiting pick up.
And the best news is that Hagen's rates are very, very reasonable. They also provide UPS and Fedex shipping services which are good for Canadians wanting to ship into the US without having to pay the rip-off prices out of Vancouver. Of course, you need to take the goods across the border, and that can be a stressful task at the best of times.
