Sounds like a great resource for the DIY'er.
I wish there were more choices here in Canada. I do a lot of my planned maintenance and parts shopping online and have items shipped to me when on a 2 or 3 day long trip to the U.S.
A lot of Vendors offer free shipping in the CONUS, and being a tightwad, um, frugal, I try to take advantage of that when I can.
I got a case of DT40 for $132 shipped from Summit Racing. Can't wait to do the fall oil change now.
