I would like to add the payment method (COD) to the confirmation e-mail subject if someone chooses a COD order.
I have changed the subject line for my WorldPay and other payment mods in their respective callback file but I don't know how to do it for a normal COD order.
can you tell me how to do this?
e.g. COD Order Confirmation#1234
or Order confirmation#1234 - COD

cheers,

Marco
