Locate the preprinted mailing address on your Netflix rental envelope, in the lower section of the front of the envelope.
Cross out the bottom two address lines thoroughly with a black felt pen, leaving only the top line, which should read: "Nearest Netflix Shipping Facility." Then cross out the bar code across the bottom.
Mail the Netflix envelope containing your return DVD. Rather than being sent to whatever mailing facility the Netflix computer had selected for you, it will now be returned to the mailing facility that is physically nearest to you, ensuring that your rental queue will be cleared in a quicker amount of time.
