Autozone for most consumables because combined price and convenience (location) to me, but you do have to know the market for the products you're purchasing. Example: oil, lubricants and filters may be very competitive but cleaners, paints and hardware not so much. I recently bought a gallon of Simple Green liquid concentrate cleaner for $18. Later that week saw the same product at Lowe's for $12!

As mentioned above they do have have a "frequent flyer" program for repeat business and used to be that equaled @$10.00 credit for every $100.00 spent. They recently downgraded that this past winter. Still there but not as generous.

I buy so much different stuff for so many different vehicles that there is no 1 place be it brick-mortar or Interweb. Quality always comes first, then best pricing, then ship time. Amazon or Ebay are first go to's
