I've sold tonnes of stuff on eBay so I'm aware of posting it tracked and all that jazz, but I've got an expensive jumper I'm selling and have heard horror stories from people who've sold jackets only to have the buyer complain and when asked to send the item back, they sent a cheap jacket that weighed the same and the seller was forced to issue the refund.
In a dispute like this eBay will side with the buyer so is there any way to prove what I'm posting is what I say it is to avoid this?
