Etsy Watch Bot

This doesn’t work since Etsy implemented bot checks and I don’t plan on fixing it

Hacky and simple bot to check for new items listed on an Etsy store.

I was following a seller but every time they listed something it immediately sold out so I wrote this. The only notification that an item was found is from the console so I just had this program running in the background while I used my PC as normal.

An optimisation would be to have an email alert or even a desktop pop-up when a new item was found.

Written in C# dotnet core using HtmlAgilityPack.
