Groupon offers the refurbished Apple iPad Air 16GB WiFi Tablet in Space Gray/Black, model no. MD785LL/A, or Silver/White, model no. MD788LL/A, for $299.99. Coupon code "MEGA3 " drops it to $269.99. With free shipping, that's tied with our mention of a refurb from three weeks ago as the lowest total price we've seen for a refurbished iPad. (It's also $79 under the best price we could find for a new unit.) Coupon ends March 23.
Note: A 30-day warranty is included, but it's unclear who backs it.
