I'm relatively new to XM. It's been about 4 years now, so I guess I missed out on a lifetime thing by a wide margin. But still, I'm amazed how drastically they cut the rates if you threaten to leave. You'd think it would at least take a little negotiation, but no. Their first offer has always been something I've been very happy with, but I think I'll put up a little more of a fight next time to see how low they'll really go.
