Does anyone know of a service for selling second hand equipment for disabled children? We have a special needs pushchair which we bought for our six year old son a year or so ago which is hardly used and sitting in the cupboard. (We don't need it anymore as he's got a new wheelchair which folds up easily). It seems a shame that it's not being used but it's kind of a niche market so I don't think putting it in the local paper will work. Any ideas?
