I saw someone in another thread suggest auto parts have gotten cheaper, so I looked up some old receipts. Sure enough, in many cases (not all) things are cheaper than they used to be.
27 Aug 2016: I bought a Saleri brand water pump for one of my MINI Coopers. $55.00 at Pelican Parts. Exact same part today at Pelican is $44.50
8 Aug 2019: Advic Brakes Pads at RockAuto: $50.79. Today, exact same price. Raybestos rotors were $49.89, today $48.79.
22 Mar 2020: MANN Cabin Filter. $12.45 at RockAuto. Today $11.83.
7 Oct 2019: Pagid Rotors at RockAuto $20.79. Today $19.52.
26 Oct 2020: Brake wear sensor $17.44 at NAPA. Today it’s $13.99
Tons more air/cabin/oil filters, belts, etc. cheaper today than anytime in the last 3-4 years.
