I used to work for Family Dollar in the FP&A org interfacing with the Real Estate Group. Effectively, as soon as one of the dollar stores gets a foothold in a small market, there's not enough business for the competition to even come in. DG has always owned the rural market using this strategy. FD always focused on urban and suburban markets.
I dont see a problem with this. We have one that does the same thing but a few generations less wild.
