Hi there! I understand your BJ's Wholesale Club app isn’t saving your credit card info even though the details are correct. Let’s get this sorted out together. To start, can you tell me if you’re getting any error messages when you try to save the info? Also, have you tried updating the app recently or reinstalling it? Sometimes an outdated or corrupted app version can cause this kind of issue.

Meanwhile, here's a step-by-step approach to try:

1. Update the App: Make sure your BJ's app is updated to the latest version from the App Store on your Mac or, if using an iPhone/iPad, the respective device’s App Store. An update may have fixed saving payment method bugs.

2. Clear Cache or Reinstall: If updating doesn’t help, try deleting and reinstalling the app. This can clear any corrupted data that may affect saving payment info.

3. Check Easy Renewal Payment Method: If you’re trying to save your credit card for BJ’s Easy Renewal service, go to your BJ's online account via a web browser and update your payment method there: log in, navigate to "BJ's Easy Renewal Payment Method(s)", click "Edit", update your card info, and then save. Sometimes the app syncs with this info8.

4. Verify Account and Card Status: Contact your credit card issuer to make sure there are no restrictions or issues on their end. Occasionally, card providers can reject saving card info on some merchant platforms due to security policies.

5. App Known Issues: There have been reports that the app may not remember credit card info reliably. If all else fails, you can reach out to BJ's app support at [email protected] for additional help6.

Does this sound like something you haven’t tried yet? Let me know, and I can guide you through any steps you’d like assistance with!
