Add a checked price
Use a product page you can open normally, with your exact shop selected. These are your confirmed checks, not automatic retailer feeds.
Saved on this browser only. Your basket uses the check until it expires, at most 36 hours or the Wednesday specials change. Export checks to transfer them to another device. Screenshots stay on your device.
1. Open the right product
Select that shop on the retailer’s site and check the original product, size, price and availability.
2. Capture the price
On your phone: take a screenshot showing the product, price and selected shop. If the shop is on a separate screen, check it separately before confirming.
Desktop browser capture helper
Drag Capture Cocobella price to your bookmarks bar. On the retailer product page, highlight the displayed price, then click that bookmark. It opens this confirmation form with price suggestions. It only reads your selection and the product-page address, never cookies or your account.
If your browser blocks bookmarklets, use a screenshot or paste the price text below.
