I don't particularly care for small talk with a seller. I really do believe that there are serious and non serious sellers. I'll wait patiently for a busy but serious seller. If my instincts tell me I'm was 'sized up' and stuck on the B list, there wouldn't be any possible deal no matter how interesting something looked a few minutes earlier. There are just way too many options for buyers.

I think, just to see what happens, a seller might price everything at an honest bottom line, and put up a little sign that explains, no dickering adjusted to best price. It may mean not squeezing a few extra bucks out one or two items, but I think the goal is to scare away tire kickers.
