Hey ladies, I'm looking for a bit of advise about selling a pram. I have a silver cross freeway travel system, one of those that is like a cot then a big pram then a buggy, with the car seat, change bag (and for some reason a spare wheel 🙃🤔) that I need to sell but I don't know how much would be fair??? I'm thinking around 150-200 but I don't know if I'm asking too much haha. Any advise is apriciated:) x
