Best Buy offers the Apple Smart Cover for iPad mini in Light Gray or Pink for $15.99. Opt for in-store pickup to dodge the $3.99 shipping fee. That's tied with our mention from two weeks ago and the lowest price we could find by $11. It features a magnetic closure, auto-sleep/auto-wake, and can be folded into a stand.
Of note, it's also available in Red or Green for $19.99, or Blue for $24.99.
Orders placed by 4 pm local time on Christmas Eve will be ready for pickup in time for Christmas.
