Gumtree or Ebay
or perhaps one of the many Facebook pages
There is a policy on this site that you need 50 posts to be able to sell.
In saying that, nobody on here ever spends any cash, of the brazillions of things on here for sale over the years,
I think the only thing that ever sold was goat and that was only because the old geezer who bought it, read it as
boat!. They seem to like boats on this site.
Good luck with your sale
