Video Business Online brings news of a cross-promotional campaign that should prove pretty exciting to those desperately looking forward to Frank Miller’s "Sin City" adaptation: "Starting March 27, electronics chain Best Buy will give out free DVDs promoting April 1 theatrical release ‘Sin City,’ from Dimension … Consumers will be able to get the teaser DVDs–which contain a trailer, behind-the-scenes interviews and scenes from the film–with the purchase of any CD, DVD or videogame." The promo DVD will also include a host of other Dimension trailers and a handful of BB coupons.
