Removing postage

[emwhitelaw]

I was wondering if someone can assit me.

I have had a bidder buy two items of mine, and requested for myself to post them together. 

How do I remove postage on an item? So I can post them together.

Thanks.

Click on send invoice/information and then where the postage charges are delete them and add the correct postage cost and send.

Do not click on recalculate.
