Sometimes doing a deal is like meeting someone face to face and you or them say or do something that makes if impossible to ever want to be friends. Some psychologists have said we make a judgement on someone in about 4 seconds. I read another post somewhere where and the guy summed it up pretty quick. Can't remember the exact wording but it was something along the lines of "The deal got P****d on right away." I don't know if there is any coming back from that when that happens. Guess it depends on personalities involved. Of course there is always two sides to the story. For the most part it seems like sellers prefer short no interaction very dry email exchanges. Thats not much fun. However by going on line you can save a bunch of money compared to the big gun shops where you can have a bunch of good old boys slapping you on the back yuck yuck yucking it up with you when your buying and a month later when you go back they don't even remember you.
So whats better - the reality of very little interaction thats just business or guys getting paid to make believe they like you. It's a paradox.
