REI Garage offers the Arc'teryx Lunara 10 Shoulder Bag in Iron Oxide or Black for $46.73. Opt for in-store pickup to avoid the $5.99 shipping charge. That's the lowest price we could by $6. (Alternatively, you can pad your order to over $50 to bag free shipping.) It fits a 13" laptop or tablet and features a removable hip belt and zippered main compartment.
