150 Darts, $7 with code DNE35H8I

After everyone else in your office has stopped the impromptu NERF gun fighting and gone back to filing expense reports and making sales calls, you alone will be able to continue running around shooting everyone, because you bough 150 extra darts for $7. I recommend wrapping your necktie around your forehead and scribbing some sharpie under your eyes; it projects toughness.
