This is Refurb by Apple. Comes with 2 year warranty and 15 day return (no questions asked).
It was for $619 before the recent Apple event (iPhone 7 launch), after which they dropped the price to $559. Note the 64GB Air 2 is not available on Apple store anymore, they have the new 32GB Wifi for $569 (10 bucks more!!).
Gold Color only.
Note - all refurbs come with a brand new body and battery, as mentioned on apple's website.
I purchased one last week, works great no issues.
~$530 with the ebay deal for a new one (import), is this really better?
