I feel like I should by one of these refill packs every time I go to the store. My kids are always needing more Nerf darts. Grab the Official Nerf N-Strike Elite Series 30-Dart Refill for just $6.96! (regularly $9.97) Be sure to select free in-store pickup to avoid shipping fees. Otherwise orders of $35 or more will qualify for free two-day shipping.
