Next summer tires for my 300m -> General Tire Exclaim UHP

My Yokahama Advan S4 tires that I bought a few years ago are pretty well
worn out, and I think the next set of summer tires I'm going to buy are
the General Tire Exclaim UHP:

The Advan's are classified as Ultra High Performance All-Season, and
they rank 6'th in that catagory, or 92%, compared to the #1 ranked tire
(Continental Extreme Contact DWS):

Previous to the Advan's I had Dunlop SP Sport 5000 Symmetrical, which is
also classified as Ultra High Performance All season.

The Exclaim UHP is classified as Ultra High Performance Summer tire,
which is nice because a few years ago nobody seemed to make a UHP summer
tire in the size I need - 225/55-17.

The ratings for UHP summer tires are here:

The Exclaim UHP ranks 4'th, at 97% compared to Bridgestone Potenza
RE760. Ranking second is the Michelin Pilot Exalto PE2, and third is
the Firestone Firehawk Wide Oval.

The Exclaims seem to be highly regarded on other high-performance
driving web sites.

Tire Rack's price (about $102 USD) is almost half the price of what I
can find locally here in Ontario (we get screwed through the ass when it
comes to tire pricing). I think I'm going to buy these through
tire-rack.

Anyone else in Ontario buy from Tire Rack and can tell me what they paid
for shipping, customs, duty, taxes?
