Well not exactly free, but you'll get a rebate in the form of an American Express gift card for the amount you paid.
New customers get all the perks. When you first sign up for cable or satellite services, the companies throw everything they have at getting you in, but after the first six months the relationship stales. You're not new and exciting anymore and they start to charge more and take away some of the cool freebies.
Dish subscribers have some good news coming their way. The company has decided - according to Satellite Guys - to extend an offer of free Sling Adapters to current customers instead of just the ones new to the service.
Technically, the adapters aren't free - at least not initially. You'll have to pay $99 up front, but you'll get a $99 rebate in the form of an American Express Gift Card. You get your money back, but you'll have to wait a bit.
