If you have T-mobile and a AAA membership, you can save 10-14% (it varies), by either: calling 611 and having them transfer you, or calling 1-877-AAA-7494, or going to your local t-mo store. Note that this doesn't work for the Even More Plus (non-contract) or prepaid. There are also discounts for postal workers, university students, and probably lots of others. Only one discount will be applied, of course. It may take a couple of billing cycles before you start to see the discount, and they may change the date of your billing cycle.
