Nothing listed for me either. Must have gone quick. I picked up my Southwest pack on the last sale through DJBennett - great deal and pack!
That being said, I check their site once and a while for other outdoor brands. As it is, all of the Icebreaker stuff that they carry is 50% right now.
Other brands they carry -- Altra, Arcteryx, Asolo, Dale of Norway, Darn Tough, Defeet, Exofficio, Gore, Grandoe, Helly Hansen, Leki, Mammut, OR, Sorel, Vasque, Westcomb, and some others that are more winter sports specific.
