Python program that emails you when a product changes prices. It also logs the price changes in a csv so you can track overtime.
Ideally you want to pair this with a cronjob or taskmanager and run it daily.
To track a certain product, change the info in the main section at the bottom (in particular the 4 variables). Along with this add your email information in the SendEmailAlert function; replacing the FROM_EMAIL, TO_EMAIL and PASSWORD fields.
The product I tested it with is the Nike Flyknits: https://www.sportchek.ca/categories/men/footwear/running-shoes/lightweight/product/nike-mens-free-rn-flyknit-motion-2017-running-shoes-black-332258744.html#332258744%5Bcolor%5D=99
