I do have selling experience on ebay but so far it's been postal only. I've just sold 2 heavy things which the buyers are collecting. One has already paid via Paypal and the other is giving me cash on collection.
I've heard so many horror stories that I'm wondering if it would be OTT of me to take a quick snap of the buyer holding the item, as well as getting them to sign a receipt? Money involved is £50 and £30.
