From what i have seen you can buy it at toys R us for 40 dollars.
you can only buy the Nerf scout as part of the unity power system which ranges about 40 pounds. another option is to look on eBay.
The Unity Power System has become increasingly rare all across the world, so if you see it in the UK I would advise that you get before it is gone.
The Titan AS-1, the Hornet AS-6 and the Scout IX-3
toys r us for forty dollars.
The Scout IX-3 only comes in the 2003 Tech Target set which is rare and discontinued, and the 3-in-1 Unity Power System, which is tough to find. Your best option is to buy one of of eBay or something.
The Longshot uses the Clip System, or Streamline, Darts and they are now standard Nerf ammunition and come with many Nerf add-ons including the Bandolier Kit and the Ammo Box. You'll find then everywhere Nerf is sold.
Unfortunately, you can't in 75% of stores. The only way to get it is to buy it online, or buy the Titan and Hornet separate and leave the Scout out.
There are several. The Unity Power System retails for $49.99 in Canada, the Capture the Flag set is also 50 bucks. Same with the Vulcan. It would have to be the Stampede, which is $54.99 in USD.
