Dollar General Testing Online Grocery Pickup

Dollar General is getting into the online grocery delivery game.  Right now, the company is working on its own program that's similar to the way Walmart and Target operate their program.  Dollar General already has a mobile app that allows you to calculate how much you're spending and at some locations, you can even pay through the app.  There's no word how many locations will take part in the program or when the program will begin.  Do you think that Dollar General will change the game with this program? Have you found that you shop online more than going into a store?
