If you list products on Trade Me using Trade Runner you can offer Pay Now/Ping and After Pay.
All listings are created with Pay Now/Ping by default.
If you want to offer After Pay, you need to enable it under "Settings --> Trade Me --> General". from the left-hand navigation.
Trade Runner does not support payment on pick up or Bank Deposit.
This is so that as a seller, you only receive orders that are confirmed and paid for.
