"EBay credits your final value fees on a cancelled transaction, but not a listing fee. Since you had a free listing, it's no big deal - but a seller who paid to list will still bear that fee."
They allow you to relist it free (if you can wait until it is not free listing time )

"New rule on American eBay (it may apply elsewhere - I don't know): if you cancel a pending listing that has bids, you will pay a final value fee as if the bid had won. You get "one free" per calendar year, and then they charge after that."
Had that rule here for some years. Not even aware you get a free one per year. Even if you do Im sure they inflate some other charge to cover it
