Dell Home offers its Targus Drifter II 17" Laptop Backpack in Black/Gray, model no. TSB239US, for $39.99 with free shipping. (Jet.com charges the same.) That's the lowest total price we could find by $20, although we saw it for $10 less in May. It's designed to fit laptops up to 17" and features multiple zippered compartments, file storage, and two side water bottle pockets.
