Amazon has the Nerf N-Strike Elite 100 Dart Refill Pack (reg.$34.99) for $17.49. That is the lowest I have seen it.
It includes 100 Darts, 2 Clips and Ammo Box.
It ships FREE with Amazon Prime or super saver shipping $35+. Don’t have Amazon Prime and need to get your total up? Check out all the latest Amazon deals (there have been a lot) and check out these add-on items.
