If you’re a DirecTv customer go to Channel 111 (you must have a box that is plugged into the phone line/internet for this to work). You have to watch the whoppers rotating for certain periods of time (5+ minutes), and press the keys on your remote at certain times to get it. You can get up to 3 of them.
Make sure your box is connected to a phone line before you do this! That is how they get your address to send you the coupons. If you don’t have a phone line, you will just be wasting a half hour of your time.
