You have to live on the rural route or in certain parts of a city to understand the dominance of Dollar General. Their business model is extremely successful. They've killed off the little country stores and made a huge dent into WalMart sales.
Since they've expanded their frozen food and grocery sections, many people do quite a bit of their shopping there and visit the bigger grocery stores less.
I suspect what's happening in Ohio is two-fold:
DG is infamous for understaffing. Their managers are given only so much money for employees and with even very flexible scheduling, many times the store will only have one or two employees. Hard to change prices on the shelves, unload trucks, stock and tidy shelves, when there aren't enough hands to do it.
Prices are changing rapidly, especially with the price of diesel ramping uo. The employees can't keep up with the computers.
