The Apple Store offers its current-generation, factory-refurbished Apple MacBook Air Intel Broadwell Core i5 1.6Ghz 13.3" Laptop, model no. MJVE2LL/A, for $849 with free shipping.

It's also available with a 256GB SSD, model no. MJVG2LL/A, for $1.019 with free shipping. That's also tied with our mention from three weeks ago and $80 under the lowest total price we could find for a new unit. Each is covered by a 1-year Apple warranty (the same as new units).
