I never have any problem getting them down to $5.99/mo for the Music & Entertainment package. For years I got them down to $4.99/mo but a couple of years ago $5.99 seemed to be the standard (which is fair given how costs for everything gave gone up). I have heard some like you say they still got $4.99 though. I'm fine with either, I just won't pay 4x that, which is the list price that no one should settle for.
I set a phone reminder to call back every year. Actually, I use the CHAT feature, since I hate doing these things by phone unless I have to.
In our Porche Macan, they had a special 6-mo intro off after the free trail was over. I think it was like $25 for 6mo, which is a little cheaper than normal. Then I'll chat again to get a good annual price.
