When an advert 'For Sale' (or Swap, Free etc.) is complete it's a good idea to mark it 'Sold' to prevent other people contacting you about it.
Find the 'Sold' button and click it (shown below).
It will change the prefix to 'Sold'. If the buyer pulls out you simply click the 'Unsold' button (shown below).
Note: it will choose the 'For Sale' prefix when you click the 'Unsold' button. If you wish to choose another prefix (Free, Swap etc.) then you press the 'More options' button '...' (top right of your advert) and choose 'Edit thread'.
Here you can change the prefix to any one you want.
