O'reilly's is about the only place I have to go around here (besides NAPA). FWIW, I have never been dissatisified with the tools I have bought from there. And like Blacknwhitepit said, their service is great. It also helps that when I am really in a bind, my dad has a business account there that I can charge to. I work about 20 minutes from home, and I prefer to go to the store in the town I work, but its nice having another one along the way home. Typically, if the store in Weatherford doesn't have what I need, Clinton does. My father-in-law tells me he's SOL in the city with Autozone since they won't just hold the part for him if there's one left at another store, but they can ship it to that store for him to pick up the next day.
Like I said, I love O'reilly's.
