Another comment I'd add is, be persistent.
My first call a few weeks ago got me Max for $180. I called back again tonight, eventually got transferred to Customer Loyalty, and locked in a $35 credit/month for the next 12 months with no contract required. So I basically got free Max plus the leftover credits cover my NHL Center Ice package.
Granted my current contract is up in a few weeks so my leverage tonight was solid, and hopefully I'll keep leverage for next year's call by staying out of a contract. Sweet.
