I sold a Spin Bike on Gumtree a few years ago and had a terrible experience. The creep who turned up for it was asking if I'd include worn work out clothing! Luckily Crapbag came home just after he got here and he swiftly left with the bike after paying him. I've never used it again
What about Gumtree? I think that's still used for local sales that the buyer collects.
