noticed this while I was browsing ebay for nerf stuffs. it's normally $30 in retails. bigw was selling $28.xx yesterday I went there. I would have bought this if I have not bought the Retaliator yesterday :(
This one uses discs instead of darts like other Nerf N-Strike, pretty good review

Note: I haven't bought from this shop before but seems legit & currently has free shipping. Let me know if this is not the case.
Edit: shipping only free for order over $49. my apology
only free shipping if you spend 49 dollars or more?
