So I had this auction on ebay for a large hard drive. This idiot wins the auction, after winning the auction, he wants to negotiate the s/h, $20 ( iknow it's a little much, but it also covers my paypal)...I have it in the terms and agreement that bidder agrees to shipping of $20 so there won't be any confusion. I'm already selling the HD at a loss so there's no way I'm gonna cut this guy a deal on shipping. He fights it, I even offered to not sell it to him. He calls me all kinds of greedy names and stuff, but I figure that you deal with a##holes once in a while and stood firm. He finally gave in and paid up. I shipped it next morning and he got it in 2 days. Guess what? He leaves negative feedback! I stupidly already left feedback (I leave 20 at a time) so I forgot about him and left him positive feedback a couple of days earlier. How can I get back at this stupid A#hole, it's my first negative in over 300 sales....Thanks in advance for your inputs.
