I bought a new car recently and got a 3 month Sirius trial. I kept getting emails asking me to add the new car to my account, where I have another car. I didn't do that because I didn't want it to interfere with negotiating for a new rate on my other car which came up soon. I got another pestering email about the new car but this one offered a 3 month all access trial for $2 after my 3 month new car trial ended. I took that but when I used my email address it said it was already in use. So I used a different one, which created a separate account and then took the extra 3 months for $2. It may be to my advantage to keep the two cars on different accounts, but for now that got me another 3 months on the new car for $2.
