I build monitoring tools for Turkish e-commerce marketplaces.

My focus is Trendyol, and specifically monitoring rather than one-off scraping: an Actor that runs on a schedule and tells you what changed since the last run — a price move, a stock flip, a different seller on the listing, a new product in a category you follow.

Most of the work went into not guessing. Trendyol publishes more than one price per product: the shelf price, and conditional ones behind a basket promotion or a Trendyol Plus membership. Roughly one product in six carries such a price, so a tool that reports a single "price" often reports the conditional one without saying so. Mine reports them in separate fields, and refuses to record a number when the two published sources disagree in a way no promotion explains. Clothing, shoes and watches use a different page shape again, so those are handled explicitly rather than skipped.

Trendyol Price & Stock Monitor — give it product URLs or a whole category listing, and get change events instead of a fresh dump you have to diff yourself.

Happy to hear about bugs, edge cases and feature requests.
