Hi there! I understand you've been experiencing a "Checkout failed. Payment" error on the MARTIN'S Food Markets app for pickup orders for the past two weeks. Let me help you get this sorted out.

To start, could you tell me a bit more about your situation? For example:
- Are you using a saved payment method or entering new payment details at checkout?
- Have you tried using a different payment method or card?
- Are you connected to a stable internet connection when trying to place the order?
- Have you updated the MARTIN'S app recently on your Android device?

Based on what you've shared, here are some step-by-step things to try that often resolve payment issues on the app:

1. Restart the App: Close the MARTIN'S app completely and reopen it. Sometimes app glitches clear up with a restart.

2. Update the App: Check Google Play Store for any available updates for the MARTIN'S app and install them. Using an outdated app version can cause checkout errors.

3. Check Payment Method: Verify your saved payment info in the app or try adding a new card. Confirm the card hasn't expired, is activated for online payments, and has sufficient balance.

4. Clear App Cache: Go to your Android device Settings > Apps > MARTIN'S app > Storage > Clear cache. This removes temporary data that might interfere with payment processing.

5. Use a Different Payment Method: If your primary card isn't working, try another credit/debit card or payment option if available.

6. Stable Internet Connection: Make sure you have a solid Wi-Fi or mobile data connection while placing your order.

7. Check System Status: There have been reports of MARTIN'S systems experiencing payment issues recently that affected some customers at checkout, sometimes limiting payments to cash or store cards temporarily1. If the problem persists regardless of your payment method or app updates, this might be related.

If after these steps you still get the payment error, I recommend you contact MARTIN’S Food Markets online support using their contact form here: https://www.martinsgroceriestogo.com/contact-us for direct account and transaction assistance.

Let me know if you need me to walk you through any of the steps or if any new details come up! Are you satisfied with the solution I provided?
