I had my receiver hooked up to a wireless bridge forever and never paid the $5 fee. The bridge stopped working and it was a few weeks before I had time to try and fix it. Wouldn't you know it, it was just before DISH was "dropping" the fee. It showed up on my next invoice and IIRC was still on there after that, even after I got the bridge working again.
Had to call to get it removed. DISH has a habit of these "grandfathered fees" which are bad business IMO. My mother paid lease fees on a single receiver for several years after DISH started including the first receiver with the programming fees. Got monthly credits after I talked to ER, but had to call again every year when the credits ran out. Said they couldn't remove the fee, it was tied to the receiver. DIRT was finally able to get the fee taken off (thanks Mary!)
