Apple Store offers the factory-refurbished Apple iPad Air 16GB WiFi Tablet in Silver (pictured), model no. MD788LL/A, or Space Gray, model no. MD785LL/A, for $419 with free shipping. That's tied with last week's mention and $60 under the lowest total price we could find for a new unit, although we saw a new unit for $19 less three weeks ago. A 1-year Apple warranty applies.
