Hi,
Regarding the AUP plugin documentation, you will see some specific options.
www.hikashop.com/support/documentation/i...userpoints-form.html
Like:
Partial payment: Allow or not the partial payment of an order. If the partial payment is active, you are able to set a Maximum percentage of the order payable with points. When a partial payment is made, a coupon is generated for the order and the user will have to pay with another payment method the remaining amount.
Which allow you to pay an entire order if the user have enough points too.
So the payment method won't be display if the user does not have enough points.
Regards,
