"Prior to Christmas, our planned sales improvements in the winter product categories, in most of our cold weather markets, did not materialize, as these markets experience significantly less snowfall amounts than normal," the company said. Sales of hunting and camping merchandise, along with holiday-driven categories -- such as table games and scooters -- delivered below-plan results during the quarter as well. As a result, same-store sales are now expected to be down 2%. Previously, the company had expected sales to be flat. The company did add, however, that as colder temperatures "returned and snowfall occurred post-Christmas, we experienced improved sales in the winter product categories." Shares traded up $2.23 to $26.70.
