I needed a new battery, so I went to O'Reilly's. The service was extremely quick and the man that helped me checked not only the charge of the battery, but other basic engine functions as well to make sure they were good. It was confirmed that I needed a new battery, but everything else was working well.
He helped me select the battery that I needed, and even looked into the company database to find that I purchased a battery from O'Reilly's in Michigan some 4/5 years ago, so he gave me a discount for some kind of warranty that he was able to find
He then installed the battery for me at no cost, and it the whole trip only took about 30 minutes.
Great service, great products, and very very helpful.
