The Apple Store offers the factory-refurbished Apple iPad Air 16GB WiFi Tablet in Space Gray, model no. MD785LL/A, for $339 with free shipping. That's tied with last week's mention as the lowest total price we've seen for this model with an Apple warranty. (Apple charged $419 for a refurb in September; it's currently $55 under the best price we could find for a new one.) A 1-year Apple warranty applies.
