If you call XM radio and threaten to cancle, THEY WILL DO WHATEVER IT TAKES TO KEEP YOU AS A CUSTOMER! What I do is call and tell them you want to speak to customer service, then tell them you want to $70 a year speacial offer. Not only will they honor that 'no questions asked' they will also throw in an online subscription. I just did this yesterday so I know it is possible. They actually do have decent customer service, you just have to be the one to initiate it.
