If you are interested in a free iPad mini 2, they are currently Free* on 2 year contract. Can be ordered with the 100MB data tablet plan for $10/mo or above. Also, in my cart it showed no tax, so that is an added bonus. This applies to the 32GB model and the 64GB model, in both Space Gray & Silver.
