I'm sure this has been asked before, but I can't seem to find it with a search. I have been a SIRIUS suscriber for about 3 years now. Been loving the service and have 3 radios installed. One in home and two in vehicles. Now, while I have pretty much been for the merger & still happy with the service for the most part (ANYTHING is better than FM), I am a little disppointed at the "best of XM" package for SIRIUS. I was thinking of simply getting some XM equipment and adding "Best of SIRIUS". Actually, what I wanted to do is get one XM receiver for the wife's car and add "Best of SIRIUS" since she is interested in the Oprah channel and I would be interested in occasional NFL and Stern programming when I drive that car sometimes. I would just keep my other two SIRIUS radios the way they are. Is it possible to have one XM receiver with "Best of SIRIUS" at $16.95/month and then have my other two SIRIUS receivers as additional units at $6.99/month? Or will I have to pay $12.95/month for the first additional SIRIUS unit and then $6.99 for the 3rd SIRIUS radio?
