Well if Verizon is able to give them away, Samsung is not making much money. Why don't they give the Iphones away? Only way they can give the S3 away is they are getting it for next to nothing from Samsung.
I swear, I go into Verizon stores looking for Ipad Mini and these Sales guys , one after another tries to give me S3 for free with contract. One store even offered me a 50 Gift Card. I think Samsung subsidizes these 100%, that is how they can even compete.
