Three years ago, I purchased a set of tires here. About a year later, I accidently pick up a nail. They removed the nail, fixed the leak, at no charge. Last week, guess what?
Yup, another nail. Took it by, and had the exact same experience, including no charge. Needless to say, they have earned my business for life. Even if they weren't competitive, the value of shopping there far exceeds the price.
