Top Canadian retailers that will not ship internationally including to the USA

I did a quick search through some of the top Canadian Retailers and found the following that would not ship outside of Canada

Walmart

Canadian Tire

Costco

London Drugs

Princess Auto

Toys R Us

sites like Roots and mint.ca do ship outside Canada but have high shipping charges.

You may ask why someone from the UK,USA,Australia or elsewhere would like to purchase from an online Canadian Retailer.

There are several reasons mostly related to availability of product and pricing that cannot be found elsewhere.

I will be on the lookout for a Canadian Company that provides a Canadian Address, preferably in Alberta to save the 7% PST found in BC

Buying presents for Alberta family this holiday season

So I caved in and bought a couple Ipads for relatives that I have in Edmonton Alberta this Christmas.

I had to pay the 12% HST because I purchased the Ipads from the Apple store in Vancouver, B.C.

I then wrapped and mailed them to Edmonton, Alberta. Everyone was happy including me until I realized if I had bought them in Alberta the sales tax would only have been 5%. (Alberta has no sales tax, the 5% is the federal GST)

Does anyone know of a way that I can get the tax back because the product was shipped out of BC?

Might be a good reason to see who will provide me with a Alberta Address for future purchase like this. An address is Edmonton would be best, but Calgary works as well considering I have to mail the present regardless.
