Hello
I would just like to say that for shipping to Canada, I (and I presume many others) way, WAY prefer UPSP to UPS. UPS is maybe a day faster, but they charge you an arm and a leg for custom clearance. And when you aren't there, UPSP delivered packages end up at the local post office for pick up, which for most people is much closer than the UPS depot.
I know this is pretty anecdotal, but I figured you might like to know.
cheers,
