kkapuria3/FREE-Amazon-BUY-Bot — reverse-engineered prompt

Build me a browser based Amazon buying bot like this repo describes. I want something I can run in a normal browser with a Tampermonkey style userscript plus a small local Python helper server, so it works across operating systems without a heavy app.

It should let me enter one or more 10 digit Amazon product IDs and a cutoff price for each one, keep checking the item page over and over, and when something is actually in stock at or under my price it should add it to cart as fast as possible. It should be able to watch multiple items at the same time, handle the common Amazon captcha flow through a localhost helper page, and recover from out of stock pages or other weird page states by retrying.

Please keep the setup simple and the config easy to edit. If the repo is outdated or missing pieces, just rebuild the parts that are clearly described in the README and don’t pretend features exist if they don’t. Look up current docs online if you need to.
