The math on "rented" price tools is broken

If you watch a handful of competitors, the big tools are overkill — and they bill you forever.

Questions

Do I need to know how to code?

No. If you can edit a text file and run one command (we show you exactly how), you're set.

Is scraping competitor prices legal?

You're reading publicly visible pages — the same as opening them in a browser. Run it at a polite pace (daily is plenty).

What if a price doesn't show?

Some sites hide prices in JavaScript. Send us the URL and we'll send back the one line to fix it — free.

Refunds?

30 days, no questions asked.
