Yup, that's were we could have saved a bit. When we recently bought our passes for our upcoming trip, the local travel store we bought from said they were obligated to sell the tickets to us at the CDN pricing. Buying at the US pricing online would have been slightly cheaper. I suppose we could have gotten them sent to a relative's house in Seattle or a mailbox service just across the border but the price difference wasn't worth the hassle/risk compared to just picking the passes up locally IMO.
