I’d probably go to gumtree for that sort of stuff. Just be super clear in the advert, collection only. You WILL have timewasters, people wanting you to post it to the wrong end of the country etc, just accept that and ignore them.
Note of caution though, there are lots of Gumtree scammers around. Anything that involves offers buyers arranging a courier is usually a scam. Cold hard cash in your hand keeps you safe. Gumtree is simple, post add, arrange collection, take cash. That is the only way.
I was selling a fancy pants demisting bathroom mirror last week. Very convincing, engaging questions from potential buyer but said he was in Bristol (I’m in Scotland). He wanted to arrange courier then sent me link to a page that looked like Gumtree courier / payment transaction page. It then attempted to log me in to PayPal (obviously wasn’t real paypal). It was a very convincing and easy to fall for.
