You have 3 days left on your listings so you should be able to click end on each item to cancel the listing.
You will have to tick a box with a reason ie-the item is no longer available.
You will get an email saying "sorry your item did not sell" or wording to that effect.
If you have made errors in the listing that you want to correct or postage details etc that you want to change,then you can click edit instead of ending the listing.
