I just called the Ottawa store with some questions. Here's what she told me. I am interested in a few items from the designer collections so I got put through to that department.

The SA looked up four items for me to see if they would be coming into the store, or into Canada. She could locate the items I wanted, one in her own store and the rest in Calgary or Vancouver. She is not allowed to order anything from another store right away, but in a few days that option opens to her and she is going to see if she can have a few items shipped to her store. She will then ship to me.

The Canadian prices are about 35% higher than the US sale price (a bit less than that, for the shoe that I wanted). This makes sense -- that's just the exchange rate. The discount for the sale is 40%. Free shipping, no duties. You can use a Nordstrom note as well. But you can't use your Nordstrom card to pay.

I decided to go this route for some of my items. I may still order the undies and smaller price tag items from the US and pick them up -- I'm not sure yet.
