For those that order car parts for example, changing your oil, this article by MSN Autos is informative.
I presently order my engine oil from Walmart (free shipping or specified order price, low price), and I order by parts from Amazon.com.
If I am in a super rush, I might drive down to Oreilly Auto Parts for an emergency part, or for recycling of used motor oil.
I am witnessing this disruption – it is real. Amazon supply chain and delivery is a great customer experience for commercial customers, and do-it-yourselfers who do their own repair and maintenance.
