Less than a week to go, and I only saw the first TV commercial for it today... which really snuck up on me, but I think is a good thing for this movie.

Unlike Transformers 4, which had so many trailers and so much footage on TV for months before its release, it wasn't as exciting watching the movie that we'd already seen most of already.
At least with Star Wars, everyone knows what to expect, and already got excited months ago with the first few trailers... the marketing department didn't need to spend any more time or money promoting the movie, because who else is going to see the movie that wasn't already planning to. If anything, Disney's promotional partners (like Energizer batteries) is subliminally advertising the movie for them, without it being overkill.
