REI Garage offers the MSR Nook Gear Shed Vestibule in Green for $49.73. Coupon code "XTRA20" knocks it to $39.78. Choose in-store pickup to avoid the $5.99 shipping fee. That's $10 under our mention from two weeks ago, $130 off list, and the best price we've seen. It adds 15 square feet of covered storage area to Nook tents (sold separately). Deal ends September 4.
