My current Sirius deal is $7 a month, month-to-month, no annual commitment, I can cancel anytime. The $7 price is guaranteed for the first year.
I’ve had slightly better deals with 3-month and 5-month and 6-month terms in the past, but $7 a month without a long term commitment works for me.
With nearly everyone having a smartphone, and Apple CarPlay and Android Auto becoming widely available, Sirius is in for a very tough time holding on to subscribers, which is why they’ll often offer a price that’s a fraction of the list price.
