Power-Innovation via Amazon offers the Maxboost Folio Case/Stand for iPad Air for $8.99. Coupon code "XGZ3AJZ9" drops it to $5. Prime members qualify for free shipping. (Non-members can spend $35 to bag free shipping; otherwise, it adds $8.35.) That's $35 off list, tied with our mention from last spring (which required the purchase of two), and the lowest total price we could find. It's compatible with first-generation iPads.
Also available is the Maxboost Folio Case/Stand for iPad mini in Black for $5 with free shipping for Prime members via the same coupon. It's compatible with first-, second-, and third-generation iPad mini.
