Costco really is one of the best places to get tires because of the prices. Usually once or twice a year, they will offer a coupon for $60 off a set of four tires, or something similar. The best part of the deal is that the store offers free tire rotations for the life of the tires, and will fix or replace the tires within a certain number of miles. They do honor their warranty because I have had several tires replaced at Costco due to nails and other assortment of junk from my daily commute through I-495.
