Grupo de descuento familiar

Un grupo registrado de líneas familiares elegibles utilizadas para descuentos, llamadas grupales gratuitas o beneficios compartidos; No siempre es lo mismo que una factura de un solo hogar o una factura combinada.

El rango familiar aceptado, los comprobantes, las reglas de dirección y los beneficios varían según el proveedor. Algunas compañías aceptan familiares que viven separados o parejas respaldadas por documentos específicos. Un grupo de descuento, una línea representativa, un grupo de facturación combinada y el registro de usuario real pueden ser configuraciones separadas.

Para un trámite de tienda, llevar prueba de parentesco cuando la dirección o apellido no dejen claro el parentesco. Pregunte de quién es el consentimiento necesario, qué línea se vuelve representativa, cuándo comienza el descuento y qué sucede si un miembro se traslada.
