Walmart offers the refurbished Apple iPad Air 16GB WiFi Tablet in Space Gray/Black, model no. MD785LL/B, for $224.97 with free shipping. That's $16 under our mention of a refurb from three weeks ago and the lowest total price we've seen for a 16GB iPad Air in any condition. (It's also $40 under the best price we could find for a refurb today.)
