Verizon Upgrade question

[nickf126]

First off, please understand that I am NOT asking for any illegal advice.

I see that there are many people on this site who seem to upgrade their phones every 3-6 months. I was wondering how they do it. I am with Verizon, and I tried to see what discounts were available to me for the Touch Pro, but they quoted me full retail because I just got a NE2 in April 2008. Is there a discount code, or any other legitimate way to apply discounts that you guys know of? Thanks for any help provided.
