Amazon offers Prime members the SwissGear 15" Laptop Backpack in Neon Green, model no. SA6639, for $10.73 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $8.84.) That's the lowest total price we could find by $15, although we saw it for $2 less briefly in another color yesterday. It features a padded laptop sleeve which accommodates most laptops up to 15", tablet pocket, padded straps, airflow system, audio and media port, and a water bottle pocket.
