I use the Keepa website and never realized before this article that they even have browser plugins. On the website you can set up price alerts that go out via email or Telegram. That works well enough for me.

I would do that but it's very helpful to also see how often the price changes and goes on sale to know if I am getting "ripped off".

There's a price graph on their website showing the price development over time.

Same, I just set up alerts via Telegram and they popup on my phone and desktop client. Didn't know they had a browser extension.
