Wanted to share my experience with this deal. We got two new phones a Note 3 and a Droid Maxx, after about a week I still hadn't received an email or a text like someone mentioned above. I wanted 20 mins on hold, to talk to a sales rep. she didn't have a clue, so I hung up. I called back a few hours later, waited another 20 mins on hold, talked to a rep. who actually knew about the promotion. He told me I could just go into a local Verizon Corp. store and they would give me the gift cards.
So I took a printout of screen shot from the website, with my two old phones, a Fascinate (Galaxy S), and a Droid Razr Maxx. ( The Fascinate has been in a drawer for two years, where I forgot to sell it when I got the Razr Maxx, but it charged up fine). The clerk at the store, had to ask his manager about the promo, but they took both phones, powered them on to make sure they worked, and then he printed me two $100 gift cards. I went back to work and applied them both to my bill for the next month.
Someone above mentioned the VZWDEAL coupon, when I bought my phones in mid-February, I used this coupon on my Droid Maxx and got the $50 off.
