foolioshly included the price in the topic headerr, I can edit the post and the price in that, but cannot see how to edit the header!
any thoughts on if this is possible, thanks!

In the blue bar at the bottom RHS of your post there should be a "reply" and an "edit" button.

I'll leave you to work out what one to press.  FL2 now gone and have a couple of items left for sale:-

Brodit active iPhone holder + Brodit dash clip,
Bluetooth Music Streaming Module.

Hi,
^ as he says ^

and when they sell if you do the same again and change the "For Sale" words inside the brackets to "Sold" it changers it from green to grey in the forum section

GOT IT!
