We all know jewelry doesn’t sell itself. You don’t see store owners stacking counter tops with piles of engagement rings, worth tens of thousands of dollars, to be handled and picked over as a sales clerk stands passively by waiting for a sale. In fact, from the moment your front door opens, it’s game on. You start selling a customer the moment he or she walks through your door. Great customer service is important at all times of the year, but during the holiday shopping season it’s particularly critical and takes some extra thought and planning.
