We all love shopping online, but that sting hits hard when you buy something and the price drops next week—or you realize you missed a better deal. In this video I walk through Coupert, a free browser extension that’s built to stop the guessing and help you actually know you’re saving. It runs on the major desktop browsers (Chrome, Edge, Opera, Firefox, Safari) and even works on Safari mobile, with over 9 million users and support across a massive list of merchants. I break Coupert down into three practical features. First is automatic coupon testing at checkout—no more hunting for codes that don’t work. I show it on sites like Macy’s and how it quickly runs codes and applies the best one (like finding $20 off). Second is cashback: you activate it before you buy, then withdraw earnings via PayPal, gift card, or bank transfer (average processing time is about 50 days). Third is price comparison, where Coupert can surface the same item cheaper at other retailers (think Amazon vs Walmart/Target), stacking another layer of savings. It’s straightforward, transparent about how it earns, and especially useful during holiday sales when every purchase can be optimized.
