REI Garage offers the MSR Nook Gear Shed Vestibule in Green for $49.73. Choose in-store pickup to avoid the $5.99 shipping fee. (You can also pad your order over $50 to bag free shipping.) That's tied with our mention from a month ago and the lowest price we could find by $18. It adds 15 square feet of covered storage area to Nook tents (sold separately).
