Got my credit card charge from mobilecityonline. The US$689.94 was charged as CDN$750.37. Then there was $97.26 duties/taxes on top of that. So ordering from mobilecityonline ends up costing just under CDN$850 for the N900 (with priority shipping). Without the more expensive shipping, it would likely be about CDN$825, which is pretty much exactly what it likely costs to go with expansys.ca.
