I have a single product only and one price inc delivery. When a discount coupon is applied successfully and the checkout reaches out for paypal I get the following error:
Oops! An error occurred while processing your payment.
10413 - The totals of the cart item amounts do not match order amounts.
The totals of the cart look wrong:
Product Total £149.00
Coupon Discounts --£30.00
Order Total £148.80
Looks like the discount is showing twice but applying once and therefore not adding up.
Is this a known error again?
