I want to change delivery method on a sold item

[4261sheep]

I listed an item for sale with the buyer to pay postage by royal mail I have since found the parcel is too long for this to be affordable so wish to change to a carrier which the buyer is happy for me to do  but can't find how this is possible on ebay

If someone has bought it it's best to cancel/refund and relist, opting out of Simple Delivery so you can choose your own postage.    See how to opt out of SD for large items on here:
