Best Buy offers a selection of Incase backpacks for $21.99, which is nearly 37% below list and Incase’s current asking price. You’ll have to pad your order up to at least $35 to get free shipping or opt for in-store pickup.
Campus Compact backpacks are built to accommodate up to a 15″ MacBook in its fleece-lined laptop compartment. It also features two external zippered pockets, adjustable shoulder straps, and a padded mesh back to prevent sweaty backs.
For what it’s worth, I’ve been using an Incase backpack to travel with my MacBook Air for a couple years and absolutely love its style and durability. I highly recommend it.
