That doesn't match what I have seen in similarly distant from Civilization places.
What I saw was that the prices of a newly opened WalMart in Cold Lake Alberta, were the same exact prices you could find in the city after you drove four hours to get there.
Some of the small businesses took a beating. But they were generally the businesses, that were screwing their customers over in the first place on price. They deserved to lose out!
I recall talking to the local bicycle shop owner, who was genuinely worried about WalMart and CTire coming there. In the end, it was nothingburger to him, as the chain stores did not service the market that he was interested in, with well built and repairable, but not inexpensive, bikes.
I recall seeing a item about the Northern Communities using Amazon Prime to buy groceries from down South, and that Canada Post was getting raped on the shipping costs. Dunno if they have made any changes on that front since...
We seem to be in an incredibly stupid time, as far as being able to reasonably and reliably source the ammo and components we need or want, seeing guys pimping primers for a buck each, and hundred bucks a pound for any kind of powder. It'll be kinda nice if there is still a industry left supplying this stuff, once all the effed up circumstances that are driving it stupid, finally settle out.
