Sorry, you're having trouble checking out. Usually, check out errors occur if you're using a promotional code that is not compatible with the order or there is an issue with your payment method itself. You can try removing any promotional codes currently in use or reach out to your payment method provider to see if there are issues. Beyond that, I'd recommend getting in touch with support. They would be able to provide you with more specific information as to why the payment is failing. Hope that helps.
