If you are lucky enough to have and email address that ends in .gov, .edu, .mil than you will be happy to know that many companies like AT&T gives discounts. The discount can be like 15% off you bill or on accessories. Just enter you email address to qualify in the box on the right of the page for discounts.
If your email address doesn't qualify you instantly like mine, you can still get the discount by bringing proof to an AT&T store.
Also, many hotels have Government discounts, and some office supply stores will have teacher discounts.
I heard that Comcast might even offers some kind of discount for those of us in the Public Sector, but I haven't been able to find anything online.
