*We strongly discourage sellers to end listings early because it undermines the trust buyers have in the eBay platform. eBay buyers are told that their bids are binding. Equally, buyers expect the auctions they bid on to conclude successfully.

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.*
