...should know about? Getting ready to join Dish network, I am a snowbird and can move it with me when I fly South/North. I was told to purchase extra boxes off of Amazon rather than renting as a way to save $. My question is there any further $ I am unaware of. I used a referral which gave me and my niece $50 each, am going to order the sling which will be free after rebate. I tried AAA, AARP, Costco,credit cards and found no offers for Dish just Direct and I find the 2nd year to expensive so opted for Dish.Thanks in advance 8-)
