mwave offers the Datashell Robust Armor 15.6" Laptop Backpack in Steel Silver, model no. CBP-AT15-SR, for $34.99 with free shipping. That's tied with our mention from last week (which was a different color) as the lowest total price we've seen for this case. (It's also a current price low by $65.) It fits laptops up to 15.6" and features water repellent fabric, padded shoulder strap with cellphone pocket, and more.
