Has anyone tried this deal?

I am looking to upgrade me phone. I have an old broken droid and I'm looking to get the Iphone5. I figure it's time I make the leap. I came across the deal from studentrate.com and I was wondering if anyone has checked it out before. It says I can get 10% off my monthly bill. I can really use that, so if anyone has tried this link and found success can they please tell me.
