I'm guessing you call them and haggle for a minute or 3?Seems expensive. You can generally get Sirius for $5/month per vehicle if you call and say you want to cancel.
For those that want to just "get it done" with minimal talking, they'll usually offer $100 per year to start off (which will typically come out to $120 after adding fees and taxes and other stuff). Or, if you try to call them when there's nobody around (call late, or check what time the agents are done for the day), choose the menu option on the automated audio line to cancel, and they'll try to keep you on with the same $100 a year price to renew right then and there.
It's $10 a month instead of $5 a month. I guess I could stand to bring it down lower, but sometimes, it's nice to just "do it and have it done". $35/month is a "hell no" though.
