Revising a listing after a bid has been made

[velvetchick]

I typed the words "free postage" in to the title of my item in error but stated the postage price in the description. I didn't realise thisuntil the after the item had a bid. I'm trying to revise the listing by writing a note in the box below the description but it keeps askling me to enter a valid postage policy. I don't need to change that part. Can anyone help? Am I now obliged to provide free postage?

You're not able to change postage details or the title after a bid has been placed, so I think the best option would probably be to end it and relist with all the correct details. In real terms, what is entered in the postage section will apply, but because the title is searchable, it could be construed as misleading and/or keyword spamming.

You will need to cancel any bids before ending the item.
