Shipping US to Canada
We found quite a variation in shipping costs, so we sometimes selected a vendor more by shipping costs than item costs, and not all vendors will ship outside the US. We went for the convenience of having the vendors ship to ETI, rather than us receiving, maybe packaging things together, and then reshipping to ETI. No idea if we could have saved money doing that. We looked for vendors in Canada, but only found one for a grab bar in the bathroom. (We haven't ordered Umbra hooks yet.)
Our custom fabric came from Sailrite, who charged us almost $55 US to ship 13 yds of fabric, plus ETI was charged nearly $30 Canadian for Custom's fees when it arrived there, which of course went on our bill.
The exchange rate is still very good, but not quite as good as a few have gotten recently: Our bank wire transfer took two days from California to Canada and was converted at a rate of 1.1947 on 4/23/15. From the Bank of Canada rate on that day, it looks like fees ate about 2%. We also paid a fee of $45 to our bank, which I thought wasn't too bad compared with a Cashier's check for $7.50 plus whatever UPS or Fedex would charge for one to a couple day delivery.
