Dollar General Corporation ( DG - Free Report ) is committed toward ramping up investments in the wake of rising competition from the likes of Dollar Tree ( DLTR - Free Report ), Costco ( COST - Free Report ) and Ross Stores ( ROST - Free Report ). The company's everyday low-price model is anticipated to continue to drive traffic despite the rising popularity of online retailers. We believe that store expansion initiatives and continued restructuring, as evidenced from steady store openings and the improvement of distribution centers, respectively, should keep driving higher revenues.
