Waldo starts by collecting electronic receipts from your inbox to find out what you’ve purchased. Please note that Waldo only works with Gmail inboxes at the moment. We're planning on rolling out and update to allow Yahoo!, Outlook, AOL, etc. inboxes to work in the near future!

Waldo only collects data that helps get you the best price on the products you’re purchasing. This includes information such as product SKUs, pricing, color, size, and quantity. This data helps Waldo track products online for price drop detections.

Waldo continuously monitors prices on millions of products daily. When a better price is found, Waldo gets to work, claiming the difference on your behalf.
