I just used this technique of price-matching from the internet, and successfully ordered 3 of these Endurance tires in ST225-75R15 for a grand total of $267.33 shipped, and including installation at a local Goodyear dealer. I just google-searched the tire by size, and it came up with a site advertising them for $69.99. Thanks for the tip! Here's the website I used to get the price match:
