I've been buying and selling gear for the better of 2 decades. The "best price?" question either gets ignored or I point out that my price is "fair" and "right in pocket" of the going rate. I'm trying to sell to the end user to maximize my profit/cost recoup. I find that those (not even introducing themselves and) going right for the "best price?" are resellers. They're trying to scoop up gear, to fill their inventory, as they have the overhead and storage to sit on something until it sells. I refer to them as Yard-Salers; trying to grab that Action Comics #1 before granny figures out what she has. I also call them Horse-Traders, as when they've sat on a boat anchor too long, they'll try and trade me their crap for my potentially good stuff. I understand business is business, but half these guys are scum.
