A RadioShack in Montana is making headlines — and doing a brisk business — by offering free guns to new Dish Network customers.

"Protect yourself with Dish Network. Sign up now, get free gun," reads the sign over the door of a Hamilton, MT, RadioShack. The promo has been running since October and the store's owner says it's tripled the business in that time. It's also made the store a bit of a local landmark.
