I am surprised to read all the bad reviews. Capital One Shopping regularly puts coupons on my purchases. Stuff I would never find even if I had the patience to look for them. If that was all it did I'd be happy - every dollar helps when you're old and on SS.

Haven't found many discounted items through the Amazon site

The app does not work.

Don't seem to get alternative sources; just 'discount' codes that rarely work.

Saves me even more money!
