nothing wrong with playing micky the dunce. And I stress that cash talks, i've sold a LOT of ski's and I almost never negotiate over the phone.
another classic that I run across all the time is a couple of guys will tag team and low ball with $300 txt offers and then another guy offers $400 which now looks attractive after the two first crap offers. Sellers generally get frustrated quite quickly with CL people, lowballers, no-shows, and tire kickers, after the first couple of clowns annoy them then are very receptive to face to face: cash-in-hand, "I'll drive away with it now" offers.
