I bought a pair of Dunlop Radial Rover A/T's from Tire Rack. Ordered them late on Thursday night and Monday the UPS guy dropped them in the lobby at work (where I had them delivered).
I have nothing but good things to say about them. Great selection, great prices and the shipping was actually pretty reasonable, from what I remember.
On the other hand, if you're in Canada, not sure how the customs and shipping will affect you price-wise.
