Here are some steps you can try to resolve the problem: Use another bank card: Sometimes our customers in France experience payment problems due to local banking restrictions. Trying another bank card may help. Private Browser Window: Occasionally, browser settings or cookies may interfere with the checkout process. Please try to make the purchase in a private browser window (incognito mode). Alternative payment methods: We support several payment methods. Have you tried using both PayPal and Shopify payment options? We hope these solutions will help you complete your purchase. If you are still experiencing problems, please let us know and we will investigate further.
