I have a problem with paypal. when customer using their account balance to checkout.
if the balance is enough to cover the whole cost, the total cost will become zero.
But how to customer checkout in this case? Since it will lead buyer to paypal checkout page and taking the whole cost if cost in zero.
and I am asking if that possible still checkout when there is not cost needed when using balance.
I am think of using COD, but this will lead to some buyer not using paypal and using COD but not actual payment.
Please help
