As for terrible customer service, see the below for my reasons for cutting off Prime:

In particular:
• Prime shipping is no longer certain to be two days.
• Those which are assured to arrive within two days don't always do so, but I never get a credit for that delay against my prime membership for a failure to meet their SLA even though I'm supposedly covered with some sort of guarantee.
• Prime shipping is no longer certain to source from Amazon warehouses.
• And worst of all: Amazon commingles Amazon-sourced with FBA merchandise. I've had numerous issues with counterfeits from "sold by Amazon" listings in the last two years because of this.
It is shocking how many times something that says `sold by Sony` or `Amazon` yet I press `inventory` on the menu that the extension injects into the product page and surprise, surprise, most of the stock is coming from FBA sellers.
imagine a more consumer-oriented extension that could list whether a given amazon product was likely to have commingled inventory or not - do you think this is possible?
Take a look at the information it displays: https://i.imgur.com/ZbgfSlo.png
Ignore the price bit, it normally shows the price right but there must be a minor transient issue right now.
But as you can see, Amazon claims the product is sold by Sony. However most of the sellers are not Sony.
As you said, having a customer-oriented variant of this functionality would be an amazing feature for a browser extension.
