If your contract is running out, here's a deal recently got from Retention at T-mobile:
Good TMobile Retention Offer
I was out of contract on the 2 lines in my Tmobile account, so I called in to see what they could offer. This is what I got:
$49.99/month Family Plan
My Faves
600 Minutes
N&W free
Mobile to mobile free
2 year contract
kept my 12% employee discount
It's a good deal considering that the cheapest My Faves plan is 400 minutes for $70/month, and the cheapest non-My Faves plan is 700 minutes for $60/month.
I know there was a deal going on for free my faves on any plan when you called retentions, so this may be only saving you $10/month if you really don't need 700 minutes, but it's still cheaper than any other carrier.
