Are you saying you're on paperless billing and got the coupons? If so, did they come in the mail, or did you find them online? I've been a Dish customer about 13 years and am on the paperless system, so I'm wondering if I got passed over or if I'm not looking in the right place.
Yes, I am (and have been since they started offering it) on paperless billing and they did send them to me in a big red "Thank You" card in the mail. I've gotten them the same way before and they usually correspond to the price increases. I've never used them before for the reasons previously stated.
