The Apple Store just got filled with refurbished iPad Airs in a few varieties starting at $419 for 16GB and $509 for 32GB in both Space Grey or White. That’s $80/$90 off the new price and the lowest price we’ve seen for iPad Airs with Apple’s 1 year AppleCare warranty (we saw them new for $430 last week). Apple certified refurbished products look and act like new, come with all manuals and accessories, a new outer shell batter and come in a new white box.
Walmart still has refurbished iPad Airs for $399 but with a more dubious 90-day non-Apple warranty. Meanwhile, if you are after new iPad Airs, Staples currently has them for $50 off across the board.
