How to Track a Product

Don't let "CSS Selectors" scare you—it's just a way to point caero to the price.

1. Find the Price: Go to your product page (e.g., Amazon, BestBuy).
2. Copy the Path: Right-click the price on the page → Inspect. In the window that opens, right-click the highlighted code → Copy → Copy selector.
3. Paste & Save: Paste that into caero along with the URL.
