If you haven’t found your way to a Costco yet, you might want to make a point of doing that pretty soon. The Nerf Stampede was reported there in a special bundle!
For the relatively similar price you’d get at Target or Wal-Mart you get 4 (instead of 3) 18 round magazines, 2 (instead of 1) 6 round magazines, a bandolier AND carrying strap, 100 darts and the Stampede/shield/bipod. Batteries still not included. HOWEVER, quantities were limited, so make sure to call ahead if your store has any left. GET ON IT!
