POST FALLS – An owner of the Post Falls Outlets, formerly Post Falls Factory Outlets, said he hopes the sprawling retail center will enjoy a bump in business from the up to 2 million shoppers annually expected at the neighboring Cabela's store, opening tomorrow. Located on the opposite side of Interstate 90 from Cabela's, the outlet stores are mostly vacant. Of the total 180,000-square feet of retail mall space, only 50,000 square feet is being leased by about 12 tenants.
