Their cable modem service is only $19.99 a month
for the first 6 months with NO CONTRACT so you can cancel at anytime after the promotion. Signing up right now also gives you $50
cash back, a FREE mp3 player, a total of 175MB of online storage, and access to over 750,000 digital songs with a free 14-day trial to Rhapsody.com. Their cable internet service is twice as fast as DSL and can even go up to a crazy 4Mbps in certain areas.
I heard that the 4Mbps service is only their base service, and for $10 more per month, you get their premier service which is 6Mbps download/768K upload!
Comcast needs you to have their service for this special offer. Please check the fine prints for details. COMCAST CABLE MODEM PROMO
