Dice Tower Review http://dicetower.com/ The Dice Tower is the premium site for video reviews. They will not review prototypes or unpublished works, but they will “preview” your game for a fee. Somewhere between $100-$200. These previews are quite useful for a KS as the Dice Tower has a huge following.

You buy bulk from here so you can cut shipping costs by almost 30% by simply buying your own boxes.
