It is great when it works

I uninstalled this app because it was useless and I am STILL getting pop ups or it, and not just on Firefox where I added it, but ALL of my browsers! AVOID THIS AT ALL COSTS!

They make it sound like BIG savings, but in truth I have never saved a thing. It might say it's $15 cheaper than Amazon, but by the time you pay shipping, it's the same or more.

I like it because when I'm about to buy something Capital One popes up to tell me if available somewhere else cheaper

Great app. No issues and save me money from time to time.

well it saved me over 40$ on a samsung ontop of my cards cashback.

apparently im the absolutely only person who cant access the rewards /account section of this webpage. doesnt matter what device/browser. there is no banalance of my rewards at top right cornerif i click anythin g account related its a perpetual cycle of login click booted out,

Can't sign in using google or facebook and they force you to make an account so they can spam you. Eat a fat one Capital One.

This addon will find valid coupons from time to time. However, it will automatically apply coupons any chance it gets and you have ZERO control over the behavior. Have a nice 25% off coupon? Awesome! This widget will overwrite it with an expired, invalid, or 5% off coupon automatically as you check out, and automatically hose your purchases. PITA to deal with this plugin and keep correcting it's unwanted automated behavior, on a slow system or connection.
