Valid question. I too am curious.  Although from my understanding, Dollar General sells items above 1 Dollar, while Dollar Tree only sells items for 1 dollar.  Meaning Dollar General could/can price up their items due to tariffs while Dollar Tree can't.

Add the fact dollar general currently sells a lot of the same exact brands for way more than a buck. Dollar tree imports tons of chinese junk and still makes a profit, at those prices.  
  
 The general adds 30% or more to the same product and pass the cost of tarrifs to consumers. 
  
 Food for thought.
