At its retail locations, Target offers the Apple iPad Air 2 16GB WiFi Tablet in Space Grey (pictured), Silver, or Gold for $499. Use this Cartwheel coupon to cut it to $424.15. (You can't redeem this coupon online; the links are just for reference.) That's the lowest price we could find by $25, although we saw a shipped unit for $24 less on Cyber Monday. (Most retailers charge $499 or more.) This 1-lb. tablet is 0.24" thick and features a 9.7" 2048x1536 Retina display, Apple A8X 64-bit processor, M8 motion coprocessor, 8-megapixel iSight camera, 802.11ac wireless with MIMO, Bluetooth 4.0, fingerprint identity sensor, Lightning connector, up to a 10-hour battery life, and iOS 8.
Update: Even better, MicroCenter offers it for $399.99 with pickup.
