Walmart offers the refurbished Apple iPad Air 16GB WiFi Tablet in Space Gray/Black, model no. MD785LL/B, for $279.99 with free shipping. That's $19 under last week's mention of a new unit and the lowest total price we've seen for a 16GB iPad Air in any condition. (It's also $10 under the best price we could find for a refurb today.)
