How much do gold buyers make?

Gold buyers (the "cash for gold" people) can make enormous amounts of money. Furthermore, you can don't have to be dishonest or deceptive to do it. My policy as a professional gold buyer was to treat every customer as my grandmother, and that every transaction can benefit both the buyer and seller. I regularly made a few hundred dollars per deal--sometimes thousands in a day. And back then gold was half the price that it is now.
