A client sent me the attached picture. His problem: he saw a different total amount on the OPC page than on the payment page.
I was able to reproduce the error:
- client puts items in cart
- applies a 15% coupon
- applies ANOTHER 15% coupon
As Awocoupon is set to accept only 1 coupon per order, only the last coupon was applied. But on the OPC page, my client saw "discount upon discount". Should he have refreshed the cart page (which obviously he didn't), the double discount would have been gone.
Is there a way to refresh the applied discount dynamically?
