I have been bitten a couple times by Amazon products that turned out to be counterfeit, because I purchased from one supplier and Amazon shipped stock from a different supplier. Most recently, it happened with a 2TB SSD that turned out to be a 100 GB drive. Of course, Amazon made it right after I sent the bad drive back, but it still is a PITA.
So, I was happy to learn that earlier this year Amazon announced that they would no longer be commingling stock from different suppliers beginning in March 2026. I didn't see this announced on the Hubitat community earlier this year, so I'm posting the link now:
Been using that term for a long time. Comes up in the IT data world where commingling of data is a security concern. Though now with AI everything is getting commingled.
Would be nice to know when you can be assured that an item you purchase from a prefered retailer was actually sourced by that retailler. I doubt they are going to "unmmingle" current stock!
One of the more common use of the term commingle relates to family finances. When my wife and I were married 53 years ago, it was quite common for spouses to commingle their funds. All family income went into a common account and all bills were paid out of that account. Back then, it was uncommon for spouses to have separate checking accounts. I did know a few couples, including my sister and brother in law, who had separate checking accounts. She put her income into her account and he put his income into his. Each of them were responsible for paying certain household bills.
Over the past 30 years it is becoming more common to have separate accounts. Today it is unusual to see spouses who commingle their funds.
It's used in ballistics to describe rounds that dissipate all their energy into the target immediately on impact by breaking apart, even into clothing, plaster board, etc., thus preventing "over penetration" (think Air Marshals who want to be able to remove a threat without CREATING one by punching a hole in the plane). The rounds basically go POOF very shortly after impact.
