Some establishments may be praying for the Yankees' playoffs hopes, or else they'll see lower sales. The Post commissioned a study that shows city business could lose $141 million if the Yankees keep sputtering. If they advance to the division series, businesses earn $26 million; they get another $54 million if the Yanks manage to make it to the AL Championship. And a World Series if worth an additional $61 million. As for the Mets, their post-season run would add another $147 million (a Mets World Series is worth $81 million to businesses!).
