Let’s stick with that. 
On a personal note, I’ve been involved with many small businesses. I know what they go through compared to companies who have Senators in the Cabinet of Government. A normal citizen versus a guy who’s there firsthand when they budget meetings start, no hearsay.
I know that hotels here owe millions to Light & Power and the Water Authority - they don’t pay. Conversely, if Joe Public misses one bill payment, your service can be cut off. Then you have to pay your bill AND pay a reconnection fee. The local dude is held hostage, while the big boys, count their coins and make Super Profit on every unit of stock they market.
That’s why I don’t believe, generally, that stores can’t afford to do regional pricing. I don’t know for sure, but I don’t default to believing that. That’d be like thinking Valve can’t manage to host a sale without the server/system going down. Apparently they can; they did it this year. It makes one wonder.
