Amazon offers Prime members the Whetstone 2-Person Tent with Carry Bag, model no. 80-170T, for $17.25 with free shipping. (Non-members can spend $49 to bag free shipping; otherwise, it adds $5.58.) That's a buck under our August mention and the lowest total price we've seen. (It's a current low by $8.) It features a zipper door, rain fly, screen, and carry bag.
