REI-OUTLET offers its REI Stoke 9 Backpack
in Neptune/Magnesium (pictured) or Amber/Magnesium for $29.93
for shipping. That's $15 off and the lowest total price we could find, although we saw it for $16 less in November. Sales tax is added where applicable. It features perforated foam shoulder straps, a hydration straw, hip belt, foam back panel, and more.
Of note, REI members can apply coupon code "MEM2013" to cut the price further to $23.93. (Not a member? A lifetime REI membership costs $20.) Coupon expires April 7.
