In all price hike scenarios, there is a concept called price acceptance and another called price rejection. Consumers reward the price hike with acceptance and punish with rejection. The voting mechanism is measured in dollars. Vote!
And key here: action speaks louder than words. Seller can't measure whine... but they'll notice cancellations... if the masses opt to reject price hikes.
Bonus: the fastest way to tame inflation is this SAME way: stop paying ever-increasing prices. If the masses do too, inflation will very quickly halt... and prices will start working their way back DOWN to levels where the masses opt to again part with their hard-earned money. If people roll over and "just pay" any price, "any" will simply rise and rise and rise again.
