They have the Red Box Diamond memo program and that in the last year has actually tripled my diamond business because of that.  The 90-day memo program has been very successful for us due to the fact of being able to have the diamonds that the customer needs on hand when they come in to have it instead of having to call a diamond vendor, having it shipped overnight, maybe having it for one or two days, and then having to pay to have it returned.  Stuller allows you to have it for 90 days and it is actually tripled our diamond business.
