In Canada, I believe they're still offering $4200 off the Traverse. I got mine at the end of May when they had $4500 off pricing. Unfortunately, I just missed an additional $500 off for dealer maintenance(ie: oil change, tire rotation, etc) thanks to dickering with another GM dealer over an Olympic Traverse.
Luckily, at the dealership I ended up buying the Traverse from, they had a 3% over dealer invoice pricing for members of my professional association, in addition to all available incentives.
Win some, lose some.
But overall, prices for any automobile seem cheaper in the States, even when taking into account the exchange rate.
