REI offers the Speck SmartShell Case for iPad mini with Retina Display in Smoke Black for $2.93. Opt for in-store pickup to dodge the $5.99 shipping fee. That's $5 below our mention from last month and the lowest price we've seen. (It's a current low by $28.) Designed to work in conjunction with the iPad mini smart cover (not included), this case is made from polycarbonate.
