I have a spare car seat gathering dust. I'm still using the one that attaches to the buggy. But if, like us, you don't own a car and cant see the point in buying a seat...have mine!We used it for the cab ride home. The only reason I got one to attach to a buggy is so I can take ds for a wee with me in cafes if the buggy wont fit!! The one going spare is simple, but undamaged etc. It's Mothercare. It may be a bit heavy to post, maybe about £10 at a total guess.But I could drop it off in north or central London, or you can pick it up. It would be a shame to chuck it out, but I need to make more space!!
