If you already have a plan with a carrier, typically the best way to get a deal is to threaten to cancel your cell and change carriers.
Generally, your provider will do their best to try and keep you by negotiating a better plan and/or deal on a new phone. I did this and ended up with a pretty sweet plan, about $10 cheaper a month than the equivalent "normal" plan you would get in a store.
