GOODLETTSVILLE, Tenn. (AP) — Dollar General's light revenue during the fiscal fourth quarter was outshined by booming sales at established stores and a very strong outlook. The 3.3 percent jump in same-store sales reported on Thursday easily surpassed expectations for 2.5 percent, according to FactSet. Per-share profit expectations for the year, of $5.95 to $6.15, is also a surprise.
