that's interesting, my parents are on the same HD preferred Plus package, and comcast gave them 50Mbit internet for only $5 more a month... when I called up they told me that is impossible.. now you are showing a 105 bill for a whole $40 more a month... btw my parents are not on a promotion, my dad called back after they switched to it to ask if it any term limit promotions where on their service and they where told no..
yet I try to get the same thing and I'm told it doesn't exist, and we are in the same town on the same package and on the same head end of course...
