I just renewed for one year by calling (800) 845-3072 and jsut mentioning the winback offer. I did so based on threads that I ahve seen here, so the option remains alive and well!!
Be sure that you have your radio number and billing info available because they will insist on using a credit card.

 

I thought this offer has expired already.

 

Shoot, that's even a better price for sure. Now I just hope they don't go out of business.
