Sears offers the Northwest Territory 3-Person Sierra Dome Tent, model no. 68-07050R-5, for $19.99. Choose in-store pickup where available to avoid the $7.99 shipping charge. That's $30 off list, $5 under our September mention, and the lowest price we've seen. It features a 46" center height and comes with a duffel carry bag for storage.
