I just saved $20 on my account. And now with my 450 minute plan, I've also got friends and family features on there too.
Go here and read the first post: New Unlimited Plan from Big Red? - Droid Forum - Verizon Droid & the Motorola Droid Forum
It seems there's mixed results if you get the friends and family or not if you have the 450 minute plan originally. It depends on who you talk to on the customer service end. Good luck!
edit: I also have 16 months left on my current 2 year contract and they let me go this route.
