No one wants to go through the dance of the deal!
Say I put a site/couch/product up for $120 - i get loads of emails, "what is the lowest you'll take?" - screw you! Make me an offer and we'll figure something out, I'm not just going to drop to my knees and knock $50 off my price like it seems so many people expect.
Obviously I've priced a little bit of "leverage" into my initial asking price, that's normal in my opinion, so the next time you see something you might want, at least have the balls to make an offer, if you can't do that you're probably just wasting everyone's time!
