A friend of ours is a dental technician; my husband called him a tooth fairy, because he made teeth and crowns, those kinds of things. Because he needed gold for his work, he charged all his gold purchases on his business credit card that gave him airline miles. Every two years, he had bought enough gold and had earned enough miles to fly himself and his wife to Jamaica for a two week vacation. I think it is a great idea to shop around, pardon the expression, and take advantage of the extra perks some of them offer to entice you. Just remember to pay off your balance every month!
