AT&T Wireless offers the
LifeProof Waterproof Case for Apple iPhone 5 in Blue (pictured), Green, or White for $40 with free shipping
. (Amazon charges the same for
Black or White/Grey
.) That's tied with our mention from last week as the lowest total price we could find in any color by $15, although we saw it for $10 less in August. It's designed to survive drops of up to 6.6 feet and it's fully submersible up to 6.6 feet.
Update: It has sold out at AT&T Wireless; however, Amazon still offers it in
Black or White/Grey for $40 with free shipping.
