price-watcher 1.0.1

Watches prices on amazon product pages

Price Watcher

This repo is a script I wrote to help watch a product page on amazon. Basically waiting to see if the product drops below a certain price.

The following will check the page and text the number 2025550112 if it finds a price < $1000

price_watcher B01FV4TAKK 1000 2025550112

the intended use of this script is as something you would throw into a cron task (or an aws lambda function like I did) and let it watch a page for you

Known Issues

I wrote this for one very specific product. It works for others (specifically ones that have a Offer Listing) but I have not had a need yet so I have not seen how robust the scrape is.

I'm down for talking about improvements if people see this and are interested. But I mostly wrote this to watch this one product for my wife. It started as a simple script but then I was having fun writing it in a somewhat maintainable way
