Numerous times I felt I didn't get my rewards. Finally tracked a bigger one for a Garmin watch. Didn't get my reward. Unsure why, won't bother contacting them.

For eBay it shows 5% off in the popup but on their page it shows 0.5%. Misleading.

Just a shady experience overall at this point.

Avoid this kind of useless shop-savings extensions that in facts can spy what you are looking on the internet, it's just collecting informations on you to profile you and similar customers to finally target ads/products/services. That's desguished spyware in counterpart to provide you a pretended nice service for free.

And just about the service provided: this kind of extensions (lots of similar exist like this one) can modify the webpages on-the-fly and also can censure some parts or search results to guide you to buy to a specific shop... instead of a concurrent. And guess who is paying the extension editor to do that? Sellers?
Just look at what this extension is requiring at the Permissions part...

Mind again before adding browser extensions!

You can maybe find coupons that still work about 30% of the time if that. Do not bother with using this if you think you'll get rewards from your purchases outside of the standard 1% or whatever your card offers. I've not received a single penny from the rewards offered through the extension. The only redeeming part of the extension and CapitalOne Shopping itself is the price comparison except when it inevitably links to a used product on ebay.

Coupons codes are outdated. "Cheaper" alternatives are actually more expensive with shipping. Used for two months everyday..

Hope you never have to change emails for any reason. They will just keep your rewards that you supposedly earned. Of course, after reading other reviews, you never get hem anyway!

I love Capital One

Excellent extension. Save me a lot of money! Thanks, Captial One!

I have had this thing for months and have yet to get a reward even after contacting CapitalOne Shopping. What's the deal?

EXCELLENT!
