Super friendly staff at this O'Reilly's and the counter guys seem to know what they are talking about. I recently bought some Monroe struts and shocks for my daughters Sonata. They had to order the shocks but had them available the next day - faster than Amazon!
I could just be in my head, but I think the house brand of parts at O'Reillys are just a little better than Autozone. I also like that they stock good quality oil filters and have killer deals on oil/filter combo's.
