This is totally legit, we did this with my wife. They'll just take $50 off the price is what they did for us, my wife got her iPhone for essentially $150. Just go to the link and put in your cell # and email address. You'll be good to go. Just thought i'd share to help the PGU folk save some cash on their next phone purchase.
Buy your next phone at Best Buy, must buy by the end of 2013.
