I cannot check out my order.

Please check the following:

• Please check if there are any out-of-stock items in your cart. (Items may go out of stock after being added to the cart. Please remove the relevant item from your cart and complete your order. If you would like to be notified when the item is back in stock, please press the "Notify me when back in stock" button on the product page.)
• Please check if your order total meets the minimum order requirement.
• Please check if your credit card information is correct.

If the issue persists, please contact WASO Customer Support with a screenshot of the error screen.
