I used to work for Echostar (Dish Network's parent) until they phased out the direct sales department.

I've since found the best Authorized National Dish Retailer that gives deals ON TOP of the standard ones Dish Network gives.
You can get a $50 Visa Gift Card, an iPod Nano, a LCD DVD Player, or a Home Theatre (in a box)

if you get service with them and send in the corresponding mail in form. They charge s/h for the electronics, only a couple of dollars for the Gift Card.
Their Number: 1-800-425-5728 Mention: PROMO CODE: MY13399
As with any service, be sure and read the fine print

and make sure it's what you want when you sign up!
