[Updated 2025.11.17] After the previous update, some users found the extension was no longer working. We’ve now released another update, so please give it another try. We reworked the code and UI, and the extension is working again with two display formats. If it stays loading and doesn’t appear right away, try refreshing a few times. It may also help to clear your cookies.

This extension is completely free and helps you maximize AMEX Offers. If you’d like to support us, please consider applying for cards through our site.

If you still run into issues, feel free to join the group and let us know what problem you’re seeing. It’s best if you can include the console log so we can investigate more easily.

Details below:

  • On an individual credit card page, you’ll now see our “Add to 4 Cards” button below the regular “Add to Card” button. Clicking it will add the offer to up to four of your cards that are eligible for that offer.
  • On the “View All” AMEX Offers page, our button appears to the right of the AMEX + button and shows +4. Clicking it will add the offer to up to four of your cards that are eligible for that offer.

If you have any questions, you can add our assistant or join the group to ask.

About

With AMEX releasing several AMEX Offers today, including T-Mobile, Kroger, and Best Buy, we’re now starting a public test of our Chrome extension. Why launch it when AMEX releases new offers? Because its first feature lets you add a single AMEX Offer to multiple AMEX cards. AMEX has already fixed the old multi-window loophole for adding offers, so manually adding the same offer to multiple cards no longer works and now requires help from an extension.

Installation

Just click the Chrome Web Store link and install it. You can use any browser that supports the Chrome Web Store, including Chrome, Microsoft Edge, and other Chromium-based browsers.

Features

The extension’s main function right now is to help you manage various credit card offers. The extension runs entirely locally, and no data is collected by this site. We may add more features in the future to make it easier for everyone to manage their offers.

After installing the extension, you can go to americanexpress.com as usual to view your AMEX Offers. After a short wait—depending on how many cards you have, it may take a little longer—each offer will display a red “Add to All Cards” button underneath. Clicking it will attempt to add that offer to all of your cards at once.

You can also click to view all offers and browse more AMEX Offers. On that page, because there may be many offers, you might need to wait a bit before the “Add to All” option appears.

Note: If you don’t see the offers after going to a new page, click your browser’s refresh button once more and they should appear.

After you click add, it will show how many cards the offer was added to. For example, this Hyatt offer was added to six cards. As for exactly which cards received it, you’ll still need to check card by card to confirm. If the addition was successful, wait a moment and then refresh to verify.

Please note: this feature does not guarantee that the offer can be added to 100% of your cards, nor does it guarantee that the current card can definitely get that offer. If you want to make sure an offer is added to a specific card with 100% certainty, we recommend using the standard “Add to Card” button instead.

Privacy

We understand that financial information is highly sensitive, so we do not collect any information at all, whether personal information or otherwise. We do not have access to your offers or any other information. Also, this extension only works on the AMEX website’s offers pages.
