If the Retailer is the one who set up the account, and if it is within 6 months from activation, the receivers are to be returned to the Retailer. If it is within 6 months and an account is canceled, the retailer gets charged back...but he can reuse the receivers. After 6 months, the customer is responsible for sending the receivers back. DISH tracks what receivers are associated with the original retailer, and a retailer cannot return any receiver for just any customer. They have to be his original customer, and it has to be within 6 months. Non-DVR receivers are re-deployed, and DVRs are sent in and DISH replaces them back to the retailer.
