Hi ..it would help to have the item #. Could be I.E. a US listing with free shipping within the US but a charge for international/Canada. Check the shipping/handling section of the listing for Canada.
In addition.. importing items over $20 CDN result in Customs charges.. duty if any, taxes for your province and an $8.50 clearing fee if by mail. By courier UPS/Fedex an expensive brokerage fee. On $168 , UPS approx $40-45. Members try to avoid courier.
