I've always saved money using Capital One.

Harrison Lowe·16 Sept 2026

I've read a lot of negative reviews so I wanted to give my positive one. I have used the shopping extension on two different computers and two different phones in the past 3 years, and it has worked most of the time as expected. I have saved money on purchases by allowing them to try different coupons and I have received hundreds in reward money that I have put on gift cards. I do have to wait on most of the reward money due to requirements that allow time for you to return mdse, so sometimes more than a few months, depending on the seller. Sometimes I did not get any rewards due to certain shopping deals I got instead, but overall, it has been a great deal for me. I do have to wait for the emails to come to me offering a great reward and click on those, make sure it activates and shows the correct reward deal, read the info that states certain restrictions, and then shop immediately afterward. The deal does not always last long, so you have to checkout soon.
