Either the broadband battles between the bells and cable companies are getting insane or Comcast is getting desperate for growth. It could be either of the two. Or something else. Check out this deal. $20 a month for first six months, $75 cash back, a free MP3 player and a free mini-vacation. Actually, I read the fine print. The offer is from Broadband Nation. “Broadband National is working with Comcast Corporation to bring you this $50.00 cash back rebate offer. This offer is not available directly from Comcast.” Still a pretty good deal.
