Can I add postage after auction ends

[shell_wello]

My auction has ended and as I didn't put postage in listing I need to add it now so the purchaser can pay using paypal. I have tried to add it to the invoice but this doesnt seem to be working.

Enter the postage and click on send.

Do not click on recalculate as it will revert back to before you added the postage cost.
