Rakuten has one for $289 - a new low by $10. Black and white color options available.
Not an enormous discount on the iPad mini, but still cheaper than you'll find it new elsewhere. Rakuten (formerly Buy.com) has it discounted to $289, free ship. That's the lowest price ever by $10 and solid $40 cheaper than buying from the Apple Store. The mini is just like the regular iPad, but just small enough to fit in the palm of your hand, making it more ideal for someone on the go. If you're holding it at a normal foot and a half to two foot distance, you won't be able to tell the screen's not Retina.
Apple iPad mini 16GB WiFi — $289 at Rakuten. Cheapest ever by $10. Apple Store is $329.
