Seems Ross is the place to go these days for G.I.Joe. Just recently people reported finding the repainted (all black) Pursuit of Cobra H.I.S.S. tank and several other canceled Target exclusive Rise of Cobra mini-vehicles.
Now PJ Donnell has posted over at YoJoe.com that a repainted Rise of Cobra Nightraven which is being called the Sand Serpent has shown up at the discount retailer. Originally slated to be a Target exclusive, this version of the Nightraven is painted in desert camo colors. It is selling at Ross for $15.99 and comes with a Star-Viper figure, not a bad deal.
