...if Verizon didn't send me multiple-page, glossy print fliers twice a week for:
(a) service I already subscribe to (basic DSL)?
(b) service they don't offer in my area (FiOS)?
I'm sure it's at least a couple bucks a month.
Plus there's the cost of all the fliers they send to people who don't have it and similarly ignore the fliers, because face it, if they didn't know Verizon offered internet service in their area at some point in the distant past, they figured it out several hundred fliers ago.
Same goes for Comcast.
