I recently bought some Boston Acoustics computer speakers off Ebay and they didn't work with my laptop because I don't have a digital soundcard. They're pretty nice speakers - brand new - so I decided to sell them on craigslist for $50. I specifically stated in the ad that they required a digital soundcard. So a guy responded and said he wanted them. He came over and picked them up and dropped off the cash. Later that night I get an e-mail from him and he says he wants to return the speakers and get his money back because they don't work with his computer. Part of me wants to be reasonable and give him the money back, but another part of me wants to just say, "Tough luck" because I clearly stated the speakers required digital. The person that sold me the speakers sure as hell wouldn't take them back just because I was ignorant, so maybe this guy should just suck it up and try to sell them on craigslist himself. How do you guys think I should handle this?
