If you are the seller, it sounds like people are showing up and not seeing what they are expecting to see. If you are the buyer, someone probably came along with a better offer that is closer to asking price. You have to do your homework, and make the ad text and their photos very clear. Price the item for what the market says it is worth. Pricing a LW3 at $3500 and Raven at $2000 might get you a sucker noob, but they will often do their research after "agreeing" to buy and then back out. Not worth the hassle.
