Staples offers the LifeProof Nuud Case for iPad mini in Black, model no. 1405-01, for $29.99. Plus, Staples Rewards members get free shipping. (Not a member? It's free to sign up.) That's tied with our mention from a month ago and the lowest total price we've seen. (It's a current low by $40.) It's designed to survive drops of up to four feet and is fully submersible up to 6.6 feet for up to 60 minutes. It also claims to be dirt-proof, snow-proof, and shock-proof. Deal ends August 11.
