Q: I want to add another store front to be supported. How do I do that?

You will need to implement a Handler and pass it to the cli accordingly. The Handler is responsible for parsing the HTML response of the store page and extract pricing and availability information.

You will need to implement the Notifier interface and expose it to the entrypoint accordingly along with passing in any constructor args from settings.yaml. The Notifier is responsible for processing and grouping items as needed and sending them upon scraping completion.
