Ending today, adidas takes 30% off backpacks and bags via coupon code "30BAGS" as part of its Back to School Bag Promo. With prices starting at $11.20 after discount, that's tied with our mention from two weeks ago as the best general discount we've seen on these items at adidas. Shipping is a flat $5, or spend $49 or more to qualify for free shipping. Sales tax is added where applicable.

A best bet is the adidas Doyle Notebook Backpack in Black/Mercury (pictured) for $80 before the above coupon, $56 after. With free shipping, that's the lowest total price we could find in any color by $16. It features a tricot-lined tablet compartment, zip pockets with organizers, mesh back panel, and more.
