AT&T Wireless is offering preorder pricing on the iPad Air 2 and iPad mini 3 (cellular and Wi-Fi models) that is USD $100 less than MSRP. MacPrices reported the savings, noting that the AT&T Wireless offer includes a 2 year service agreement. Since the difference between Wi-Fi only and Wi-Fi + Cellular is $129, this cuts the "upgrade" price to only $29 more than the Wi-Fi only models.
Right now all models are showing from AT&T as "shipping in 6-10 business days," and the same models (for $100 more) from the Apple site show as shipping in 2-4 business days. This puts the iPad Air 2 16GB WiFi + Cellular model at $529.99, 64GB at $629.99. and 128GB at $729.99. Pricing on the iPad mini 3 WiFi + Cellular starts at 16GB for $429.99, 64 GB for $529.99, and 128GB for $629.99.
It isn't often that any sort of discount is offered on Apple hardware, and when it is, usually it's offered on previous models, not the one that has yet to be officially released. So if you are in the market for a cellular iPad Air 2 or iPad mini and AT&T (plus service contract) works for you, now you have an attractive option.
