You may need to ask this question directly to the on-line store. The other way is to have it shipped to a US Post Office (people in Vancouver do this ALL the time...they pick up at Point Roberts) where you then pick it up. You have to declare it when crossing the border = having to pay taxes/import duties if any...but it can be done. You can contact the Oroville WA post office to find out if you can have something drop shipped there. A day trip to Oroville WA might be worth it...might not be. The fun is at the border.

Contact the seller directly and see what can be done. If they don't ship to Canada it is probably because it is too expensive/hard to get it across the border.

Good luck.
