Dollar General simply lacks the resources to sustain its growth

Walmart’s online discounting is undercutting Dollar General’s prices and competing directly for rural customers. The recent acquisition of Jet.com gives Walmart even greater online discounting capabilities. Much of Dollar General’s success is in offering convenient local stores in small towns where there is no Walmart. Now Walmart can serve those customers without building a store. This should really worry DG investors because the National Retail Federation reported that more Americans shopped online than instore on Black Friday.
