The vast majority of it is the extra receivers. We have a lot of TVs, so Dish worked great for us. One HD DVR and two regular duo receivers. So, that added $18 right there. Haven't analzyed the rest. It matters not, $105 is way too expensive for cable, for me.
Did the checking around with the family and have received authorization to downgrade. Tomorrow i'll be calling dish to drop from AEP to AT200 + HBO. It'll save me $30 a month.
