Junk... It's sad, they don't let you unsubscribe neither and most of it is addressed to "Neighbor" or "Current Resident" etc. so you can't even refuse it as post office doesn't allow if addressed that way.
I was getting this crap when I had service, made me feel better about canceling it too! They waste so much money that could be used to reduce service cost. How about offer a way to opt-out if we don't want your junk!
