When a salesperson gives you a price, your next move is to ask, "Is that the best you can do?" You might then counter with "And if I pay cash?"

You'll likely have the most success at independent jewelry and electronics stores, car dealerships, and flea markets. Don't try this at department stores, chain stores, or national retailers.
