Do an online search for these. I cannot remember the link. A lot of people do not believe that households with Dish Network and DirecTV will not need converter boxes. Just in case, I got my two coupons. I figured that we would use them on the other TVs, if they are not needed on the two main ones.
So, I received my two coupons for $40.00 off, a savings of $80.00 total. I purchased them at Wal*Mart, and paid $12.36 out of pocket for each.
