An economic situation in which supply is greater than demand, thereby resulting in lower prices, more choices, and greater leverage for the buyer. The opposite is called a seller's market. The recent advances in solar-panel technology have made it a buyer's market for those looking to integrate solar energy into their homes or businesses. I'd keep renting for now—if the real estate bubble bursts again, it will become a buyer's market for houses.

It is the buyer's responsibility to be sure that they are not being cheated or overcharged. In no place is the adage "buyer beware" truer than when buying something off an online classifieds ad. It's no one's fault but your own if you paid good money for a dud of a car. Let the buyer beware.
