Actually he can't do that. Breach of the contract he entered into with eBay when he listed the item. I think also you'll find he literally is unable now to end the item; the ebay server side software won't be giving him that option as bids have been made. Heh what a knob 🙄
"Ending a listing early for the following reasons is prohibited as it is considered fee avoidance:
Cancelling bids and ending a listing early because the reserve price hasn't been met to avoid reserve fees. See Reserve Price Policy.
Cancelling bids and ending a listing early in order to sell the item off-eBay. You should be aware that as well as avoiding fees, you risk fraud by selling items off the eBay website. If a member writes to you to ask you to sell away from the eBay website, please report them to us."
