Digging the Capital One Shopping Browser Extension


Usually, I avoid shopping portal browser extensions like the plague, but I recently installed one anyway and… I like it!  Thanks to the extension, I’ve stumbled upon rewards that I wouldn’t have otherwise, and I’ve been targeted for huge reward rates.  The Capital One Shopping browser extension (which does not require having a Capital One account) has made me a believer.

Why I usually avoid browser extensions

Shopping portal browser extensions advertise great benefits: earn points or cash back automatically when shopping online, automatically find the best coupon discounts, etc.  The problem is that they steal the click-through.  Suppose, for example, that a cash back portal is offering 20% back at Macys.com and that you intend to shop there anyway.  You start at that portal, click through to Macys.com, and expect to earn 20% of your purchase price back.  And you might.  But, depending upon what extensions you have installed and how you interact with them, you might not.  You might have a shopping portal extension installed that offers just 3% back at Macy’s (for example) and that extension may steal the click-through so that you earn only 3% back instead of 20%.

Why I tried Capital One Shopping

A friend told me that he had received a few great targeted offers from Capital One Shopping.  The one that grabbed my attention was 30% back at Dell.com.  Wow!  For those with one or more Business Platinum cards (which offer $200 Dell rebates every 6 months), an offer like that is attention grabbing.  After a bit of investigation we determined that the Capital One Shopping browser extension was necessary to get these offers.  In each case, he had received offers after browsing the given merchant’s website.  In other words, the browser extension saw the sites he visited and sent promotional offers specifically for some of those sites.

I wanted in on the 30% back party, so I gave in to my long held resistance and installed the browser extension.  I then visited a few sites where I hoped to get targeted offers: Dell.com, Saks.com, etc.

I’m not sure how many days passed (maybe just a few?) before I found this email from hello@capitaloneshopping.com buried in my Gmail Promotions tab:

Score! I had specifically looked at the frying pan after installing the extension.  Now, I had the opportunity to earn 30% back at Saks for anything, not just the frying pan.

Eight days later, I got this ho-hum CVS offer:

Two days after the CVS email, I got this excellent offer for IHG Hotels:

Cashback Monitor is my go-to site for finding which portals offer the best rewards at any given time.  Cashback Monitor also lets you see the past 15 months of rates for any given store.  I looked up Saks (here) and found that while we’ve seen 15% back now and then, no portal has come close to offering 30% back:

My 18% IHG offer was also better than any public portal offers in the past 15 months, but we saw 12% a few times and 15% once.  So, while 18% was really good, it wasn’t nearly as amazing as the Saks offer.

My 5% CVS offer, meanwhile, was not even close to the historic best.  In fact, as I write this, 5% is Capital One’s current public offer.  That said, most portals offer tiered rewards for CVS (e.g. 12% back for a CarePass membership, 5% back for CVS brand items, 1% back for all other items).  The fact that Capital One offers just a flat rebate is pretty good.

How I avoid click-through thievery

For many years my approach to online shopping has been to look for deals in one browser and make purchases in another.  The reason is that in the process of looking for deals, I might click on a site to reveal a coupon code and that click could invalidate any shopping portal click-through that I’d been counting on.  By separating deal hunting from buying, I avoid that kind of problem.

My solution to the browser extension problem was simply to install the extension in my deal hunting browser.  I already use that browser to visit various sites to check prices and so this fits perfectly with the Capital One Shopping’s proclivity for watching my shopping trips and sending targeted offers.  When I get one of these targeted offers I do use the deal hunting browser to make the purchase (since that’s where the extension is installed), but for all other purchases, I still use my clean non-extended browser.

Results so far

The image above shows my Capital One Shopping results to-date.  Only my Macy’s purchase has paid out so far.  The rest of the rewards are pending.  This is expected.  Most portals take a few months for rewards to move from pending to credited.

Here is some background about each of the above items:

  • Macys: Well before installing the Capital One Shopping extension, I used Capital One Shopping, without the extension, for a purchase at Macys.com because they were offering the best rewards rate at that time.
  • Uber Eats: Most portals don’t offer rewards only for customers who are new to Uber Eats.  But Capital One Shopping offers $1 each time existing Uber Eats customers place a new order.  It’s not much but it’s better than the nothingburger I usually get!
  • CVS: I normally shop CVS through the JetBlue portal in order to earn 3 points per dollar.  In this case, the purchase was so small that it was easier to use the browser extension and collect 3% back.  I made this purchase before receiving an offer for 5% back for CVS.
  • Saks Fifth Avenue: In my family, we currently have four Platinum cards that offer $50 back at Saks every six months (Jan through June, and July through December).  When I received the amazing 30% back offer from Capital One Shopping, I still had 3 of these $50 credits available.  So, I made three separate purchases through the portal in one day in order to earn 30% back for each order (plus $50 back from Amex on each order).  With one order I received the wrong item and returned it.  That explains why one of the three shopping trips shows a blank purchase amount.
  • IHG: I already had a cash booking at an IHG property, but when I received this targeted offer for 18% back I cancelled the old booking and booked it again through Capital One Shopping.  In this case, the actual amount I expect to pay will be far less than what was tracked so it will be interesting to see if they accurately adjust the shopping rewards downwards.  This is all part of an experiment I’m doing.  I hope to publish details and results in the next week or two.

Portal Downsides

Rewards earned through Capital One Shopping can be redeemed for the gift cards shown above.

The thing I hate about Capital One Shopping is that rewards can only be redeemed towards gift cards.  Worse, Amazon.com gift cards are not an option.  Many of the available gift cards are often discounted through various promotions elsewhere.  And I don’t often shop at any of the available merchants (there is no Safeway anywhere near where I live).  So while I’ll never look a gift horse card in the mouth, I don’t value Capital One Shopping rewards as highly as cash back.  I roughly value Capital One Shopping rewards at 80% of face value.

More about Capital One Shopping

First note that Capital One Shopping and Capital One Offers are two different things.  Capital One Shopping is what this post is all about and it doesn’t require a Capital One credit card.  Capital One Offers is more like Amex Offers and does require having a Capital One card.  You can read more about the latter, here: Capital One Offers now featuring many retailers.

Capital one shopping portal is a scam. I earned over 2400 cash back and cannot redeem a single gift card. Asked customer support and cannot do anything. Waited over 6 months since last black Friday.

Can your out-of-the-park reward rate be replicated and scaled? If no, it’s not worth the effort for a one-off score. If yes, is there a viable redemption / liquidation path? Perhaps additional means — such as Amazon or actual cash back — will be rolled out. Right now, only WalMart works for me. Thanks for the tip.

Question: Do you think that your out-of-the-park offers were the direct result of installing the browser extension? Might such offers be presented if the browser extension is not installed?

Tip: One can have multiple shopping extensions installed on the same browser, suspend all of them, and activate only one shopping extension at a given point in time. In Chrome, one would simply go to chrome://extensions and deactivate but not remove all shopping extensions. It’s a simple toggle.

Buying through the capital one shopping phone app seems to work well, and bypasses the possibility of getting the tracking cookie stolen by another extension. Also I’ve noticed that the app sometimes has better deals than it shows for Cap1 shopping on cash back monitor


I’ve recently been in the market for new Macbook Pro and recently received an amazing 15% cashback with no maximum from Capital One (for purchases through Adorama). I didn’t up using it, but I think that’s the best deal available for a Macbook Pro!

I have received a 15% cash back email offer from Capital One Shopping for Walmart (yes, Walmart!) and 30% cash back at Groupon. Both payouts are pending in my account. I love getting these emails!


Unstated but implied is that even with a Capitol One card you cannot turn these into Capitol One transferrable points, correct?

Usually, I avoid shopping portal browser extensions like the plague

I feel the meaning of this phrase has changed recently from “never” to “once every three months, even if vaccinated and boosted”.


Very eye-opening, thanks! Didn’t know that you can redeem it only for gift cards, bummer. I made one purchase which got me $15 so not much lost but I’ll devalue the “gift card back” by 20% for future transactions.
