Payment. In theory, only PayPal, Bank Deposit. or Cash on pick-up. In practice, you'll get people offering money orders, Western Union, beads, sea-shells, small children, etc

Ok with the rest but do not accept small children, I can't eat a whole one.

There's all manner of other numpty-ness on parade on Gumtree - ads for items that sold three weeks ago, which the seller hasn't gotten around to taking down are a highlight. Think of the worst sellers you've seen on eBay - because of its nature, Gumtree's kind of made up of those. Now imagine the buyers...

Well gee thanks for that, so I am one of the worst sellers on ebay LOL I find Guntree OK for pick up items and while you get a lot of time wasters I do not allow haggling and only accept cash.
