Depending on what you are looking far, Pep Boys may be a good choice. They have decent prices on fluids and cleaning supplies. The staff at this store is very helpful - if you ask! If you do not ask you may wonder for a while. Prices seem a little bit higher but partly because of convenience. Their service is higher in price. I have not used their service for repairs but they make it clear that they guarantee their work.
