I've had people not show when I'm selling, but as a buyer I've had good luck. I had someone out of state hold a bike for me while he had numerous other offers, and I haven't yet run into the last minute price hike. I've even bought items from out of town sellers, paid with paypal and had the seller mail the item. Risky for sure, but they weren't big ticket items and I had good feelings from the sellers, which proved warranted.
