We are an independent publisher. Our reporters create honest, accurate, and objective content to help you make decisions. To support our work, we are paid for providing advertising services. Many, but not all, of the offers and clickable hyperlinks (such as a “Next” button) that appear on this site are from companies that compensate us. The compensation we receive and other factors, such as your location, may impact what ads and links appear on our site, and how, where, and in what order ads and links appear. While we strive to provide a wide range of offers, our site does not include information about every product or service that may be available to you. We strive to keep our information accurate and up-to-date, but some information may not be current. So, your actual offer terms from an advertiser may be different than the offer terms on this site. And the advertised offers may be subject to additional terms and conditions of the advertiser. All information is presented without any warranty or guarantee to you.

This page may include: credit card ads that we may be paid for (“advertiser listing”); and general information about credit card products (“editorial content”). Many, but not all, of the offers and clickable hyperlinks (such as a “Apply Now” button or “Learn More” button) that appear on this site are from companies that compensate us. When you click on that hyperlink or button, you may be directed to the credit card issuer’s website where you can review the terms and conditions for your selected offer. Each advertiser is responsible for the accuracy and availability of its ad offer details, but we attempt to verify those offer details. We have partnerships with advertisers such as Brex, Capital One, Chase, Citi, Wells Fargo and Discover. We also include editorial content to educate consumers about financial products and services. Some of that content may also contain ads, including links to advertisers’ sites, and we may be paid on those ads or links.

    INSIDER SECRET: Online shopping portals are a great way to earn cash back or bonus points for purchases you were going to make anyway. If you want to learn more about them, check out our guide to online shopping portals.

    Thanks to Amazon Prime Day there are all sorts of increased cash-back portal rates that can easily be stacked with American Express card credits that come with cards like:

    Stack Your American Express Card’s Credits With Increased Cash Back Rates

    I like to use Cashback Monitor to find and compare the best shopping portal rates. If you’re not familiar with it, this guide can show you how to use Cashback Monitor to always get the best deal.

    These are the best rates available right now, but I expect them to only be valid for today (July 15th).

    The Amex Platinum card comes with a semiannual credit of up to $50 at Saks Fifth Avenue (up to $100 statement credit per calendar year; enrollment required). I used this credit today and stacked it with 14% cash back at Saks Fifth Avenue with Rakuten (Ebates). On top of that, I was also able to take advantage of free 2-day shipping thanks to my Amex card’s free Shoprunner membership and I got an additional 10% off because it was my first online Saks Fifth Ave. order (and I signed-up for the Saks email list). Overall, I placed an ~$83 order that will only end up costing me ~$7 out of pocket—That’s a savings of 91%.

    You also could use your Amex Business Platinum card’s semiannual Dell credit of up to $100 (on purchases in the US; up to $200 credit per calendar year; enrollment required) and earn 15% cash back at Dell through TopCashback.

    The Amex Gold card has a monthly up to $10 dining credit, which is valid at Boxed (enrollment required; up to $120 per calendar year). Right now you can get 10% cash back on Boxed purchases through Rakuten (Ebates). It might not be that much savings on a $10 purchase, but something is better than nothing.
