Thanks for writing this post! Being newly retired, I'm always on the hunt for ways to save money, and I had heard of Capital One Shopping before. I wasn't sure if it was legit, but I gave it a go based on this article and I'm so glad I did.

It's so cool to save a few extra dollars a month without having to do much!

Haha we are in the same boat. Another recent retiree here! I was shocked that I could use this on ebay and Macys too. I’m going to buy myself a new sweater with all of the money I saved.

A few days later - I’m back and wanted to say it’s become my most used tool!

This is really cool. I was kind of expecting this to be a scam or install malware on my computer, but I have been pleasently surprised at how easily this work. I save around $5 per purchase, which is unexpected, as i basically don’t need to do anything.

I clicked on this page via a link on CNN. I am happy that I found this by accident because I am just about to restock my pantry. I saw that I could save $3 on my husband’s favorite cookies, so he is going to be really pleased.

To quote my son “It’s legit!” I use it for all of my purchases :)

I am usually a sceptic when it comes to these type of things. I usually prefer shopping in a real store and seeing the objects. This moment in time, it’s really hard to do that so I have been buying a lot of stuff online. I am actually feeling good about this now knowing that I would not have been able to save so much money if I had have purchased from a physical store. I am have saved a lot of money since using it.

Oooh yes! You just described me. I have to say that I now too actually prefer buying online than in a store. I have my favorite products on a price watch to see when the price drops so I can get the best deal.

You know what: There is one really bad thing about this extension: Realizing that I spent more than I should have PW (pre Capital One Shopping).
