well go to your deactivated
And you will see standing at each item edit
Add a price and youre done

Just adding more detail to the first response...

1) Click on "Shop" at the top left of your screen under the banner.

2) Click on "Deactivated" on the left hand side of your screen.

3) Scroll till you find the item(s) you bought that you don't want.

4) Click on "Edit" or the picture of the item.

5) Add a price to the item.

6) Click "Update".

That will put the item on the market for other people who are looking for it to buy it. Hope this helps.
