I don't think you're off topic with that... but maybe you thought this was the best place for it.
Whatever... I don't know anything about Seattle, but do you think you're going to do better than the pricing at an online store like Yamaha Sports Plaza?
Just mildly curious. I haven't found any storefront in the US that has better pricing than the places like Yamaha Sports Plaza (which is one which also has a storefront operation). I patronize my local Yammy dealer on their more reasonable stuff, but mostly they aren't even close in pricing - and they're a pretty big dealership themselves.
Most of the bigger border crossings have businesses on the US side that will charge a reasonable fee to have your purchases shipped there for pickup, if you're driving down.
