We are looking at buying a second TiVo. I have had a Standalone Series 2 (240... model) for several years. I should have bought the lifetime sub when it was available, but I didn't. I've (almost) come to terms with that. I see on the TiVo website* I can buy a dual-tuner series 2 for $100, and add 3 years of prepaid service for an extra $300. (Saving $168 over 3 years for a first-unit buyer, if I am doing my math right...) Since I have an existing sub, I qualify for the multi-service discounted rate of $7/mo for this new unit. However, then I can't prepay. Over 3 years, my total service would be $720. Which leads me to my question: Can I buy a 3 year prepaid plan with the new unit and get MS Discount on my existing unit? If that was allowed, I could save $132 or so over the 3 years. * Which I apparently can't name due to my limited post history.
