Dell Home, via its Member Purchase Program, offers its Dell Energy 2.0 15.6" Laptop Backpack in Blue, model no. F5W83, bundled with a $25 Dell Gift Card for $56.99. Coupon code "BAG10" drops the price to $51.29. With free shipping, and assuming you'll use the credit, that's the lowest total price we could find by $27, although in January we saw it for $6 less. It features three separate electronics compartments and durable ripstop nylon construction.
Note: Dell's MPP is available to select groups, including students, government employees, military (active and retired), credit union members, and health care workers.
