REI Garage offers the Burton Big Kettle Backpack in Desert Sunset or Satellite for $16.73. Opt for in-store pickup to avoid the $5.99 shipping fee. That's $6 below our mention from last month and the lowest price we've seen. (It's the best deal now by $13.) This 26-liter backpack features a padded 15" laptop sleeve, main compartment, front pocket, and zippered closures.
