Come the new year I want to start a subscription with Dish Network. As I was perusing the site, I noticed I have the choice of doing an 18-month commitment or no commitment at all. From all the stuff I read. The commmitment says I get the 50 bucks back on my first bill plus the protection plan free for the said commitment. Now I don't really want to have a commitment since I only have a few months on my lease. Going that route, I spend the 50 bucks only, or do I incur any extra fees and such?
