For the first time in my 13 years on eBay, I hit a buyer which will not pay for an item they won. I am not concerned about reselling it or forcing them to purchase it, however I feel as though they deserve negative feedback for this. My fear is that, by giving the user negative feedback, they will give me negative feedback. Is it possible for them to do so without having paid for the item? I do not deserve negative feedback, however I fear the whole reciprocation thing.
