Best Buy offers the Incase Campus Compact Laptop Backpack in Black for $21.99. Opt for free in-store pickup to avoid the $3.99 shipping charge. That's $8 below last month's mention and the lowest total price we could find by $20. It features two external zippered pockets, padded shoulder straps, quick-access pocket, and fleece-lined compartment for 15.4" laptops, notably the Apple MacBook Pro.
