We have added another "Cash On Delivery" payment option called "Cash On Delivery (2)".
Cash On Delivery means users can get through the checkout process without having to enter an actual payment.
This is useful for providing invoice-only or cash-on-collection options.
For example you may allow cash-on-collection for people in UK shipping zones (by ticking the applicable zones displayed) and invoice-only for customers in foreign countries.
To set up this method go to Payment Processors Manager > edit Cash On Delivery (2)
