If you do not have two items you must cancel one as you may get two buyers, one item, andn one big headache.
There are only charges if there is an applicable listing fee or you added any listing upgrades, e.g. a reserve.
Go right of the item More Actions >> End item. or if on the seller hub page, tick the little box left of the item scroll up to Actions >> End
Just checked your listed items, there are no duplicates there.
You must amend your postage, you are inviting scammers by showing you do not know the correct methods of postage.
1st Class Postage is only suitable for items up to £20 in value. In my opinion it is VERY unwise to start at such a low price.
