Can I just say that all things being equal, Amazon is up there with the moon landing and transistors in terms of innovations.
I have been incorporating my "new" (that is, hot-rodded) iPod into my life. It has no bluetooth, so I needed a cord for my Bose speaker upstairs and I needed a cord for my stereo that I listen to while at work. I also needed a connector for my car. My BMW has a special cradle that integrates it into the car; boom, Amazon, delivered to my door. I needed one 1/8" stereo jack (male-to-male) with a 90 degree end, boom, Amazon, $6.00 at my door in two days. Bonus glory: it was $6.00 for TWO, so I don't have to switch them out.
I use nitrile gloves when working on the car, and I ran out; went to the auto store, sold out (COVID). Went to the OTHER auto store, sold out. Third one, sold out. Amazon? Boom, my choice of sizes, delivered in three days. I don't even know how it's possible in some cases.
