Many times on the EE other things will put me off a deal other than price. Things like Trader rating, how the ad is structured (apparent attitude of the seller) ect. can make or break the deal as well.
Example: PRICE FIRM, TIRE KICKERS AND LOW BALLERS WILL BE OPENLY MOCKED. ALL SALES FINAL, EMT ONLY.
Most folks won't take offence with the above, but for me my back is up already. There's no such thing as PRICE FIRM or I don't want to deal, the prices are asking prices. The real question is the asking price fair? To openly mock (whether this is in jest or not) doesn't attract me to even open the line of conversation for fear of being labelled a "low baller". "All SALES FINAL" leads me to believe the individual has had issues in the past with unsatisfied fellow gunnutters who have purchased misrepresented items.
"EMT ONLY" tells me the individual doesn't want me (the potential buyer) to know his name, address, etcetera. Now why would that be? Nah. NO SALE! (too risky/sketchy)
