Take a $100 off the Apple iPad Air and Mini with Retina Display and get 200MB of free data per month for life when you get them on a 24/mo installment plan at T-Mobile. As a bonus, you can get a monthly bill credit of $10 through 2014, making the 1GB data plan free if you add the tablet to an existing voice plan. With each tablet costing only $10 at purchase, this is the lowest upfront fee by $420 and the best deal for the 4G capable iPad Mini with Retina Display by over $110 when you compare it to other major carriers on a traditional 2-year contract. Plus, the shipping is free. Sales tax is charged in most states.
