Looking for what the community says about this issue. Yesterday I PM'd a seller about a pistol he had up for sale/trade. He was asking X pistol + $150 cash for his pistol. I found his asking price to be acceptable so I offered him exactly what he wanted. My pistol (X) is in pristine condition and has had only 1 mag through it. Additionally it has all the bells and whistles that are associated with it. He agreed to the trade and we decided to meet up today at 8pm. A little while after agreeing to meet up he sent me another message stating that he wanted more cash even though his original post had the cash value he wanted. In fact the add still says he wants X pistol + $150 cash (though it is closed now and he's making a deal with someone else) Am I just upset that I lost out on a deal or is this a legitiment cause for negative feedback?
