    We have had inquiries asking if we will give the new customer some of the credit instead. Our answer to that is that we want to reward our loyal customers. If the existing customer decides to give their friend a cut of their credit then that is their choice, but our reward will go directly to the existing customer. 

    See the attached document for more details on the program, the “fine print”, and the referral sheet which must be completed prior to any inquiry from the new customer.
