BuyDig offers the Griffin Survivor Case for iPad Mini in Green/Yellow, model no. GB36291, for $18.50 with free shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's the best deal now by $9.) This military-grade case includes a clip-on stand and is designed to protect your device from dirt, sand, rain, shock, vibration, and a host of other extreme conditions.

Update: The price has now dropped to $17.50.
