Highly recommend them; I've ordered from them several times: good prices; good advice; good service. They'll ship to you in Ontario for a reasonable cost (Canada Post) however you may wish to:
-see if your dealer will match their pricing (show the dealer your BuyKippScottGMParts.ca written quote). Other members of these Forums have obtained a price match in that fashion;
-find out if you've got a local GM OEM parts wholesaler that might have similar pricing, so you can save on ship costs or personally pick up the parts.
Good luck! And Happy Thanksgiving to all!
