Dollar General will be a Retail force to be reckoned with! Their aggressive plan of "everywhere is 15 minutes away from a DG" is going to help. The convenience is there. I never shop at DG, but now the convenience factor, I've done more business with them. Their stores are on my travel routes more often and you always forget something.
Now if they can get into the fuel market, with gas islands at their stores, they are going to take even more business away, then they might start selling pizzas like Casey General Stores, etc. Used to be DG was one store, in every town with other stores, now they are more rural, they will have opportunity to grow into other markets.
