Any Roamio Lifetime deals for existing customers?

I have 3 Tivo's (S1, S2, S2) all with lifetime service and I'm looking at possibly purchasing a new Roamio but I was wondering if there were any deals out there better than what Tivo was offering me over the phone? Here's the deal:

Base model Roamio: $149.99 (Orig $199)
Lifetime Service: $399 (Orig $499)

Total $548 (Plus Tax/Ship)

I've read some messages where folks are getting lifetime service offers for $99 but I don't see any such existing deals.

Thanks!
