I get real market value, a clear deal score, potential issues to watch out for, and even negotiation tips right on the page. It honestly feels like cheating. I’ve stopped wasting time on overpriced listings and started spotting legit deals instantly. The extension is fast, accurate, and fits perfectly into the way I already browse. Highly recommend it to anyone who buys, sells, or flips online. Total lifesaver.

Underpriced makes online shopping so much easier. Instead of guessing whether a seller is overcharging, the extension instantly gives me a full breakdown — fair price range, deal quality, warning signs, and even how much profit I could make if I flipped it. It works smoothly across every marketplace I use, and the insights are actually accurate, not random numbers. I’ve already saved money on my last few purchases thanks to the market value check. If you shop online even a little bit, this extension pays for itself within the first day. Absolute must-have
