Probably all in the supply change. When whatever circumstance that caused the price increases goes away the prices remain unchanged. People accept the price increases and sales continue - best way to judge a fair price. The correct price is whatever people are willing to pay. Political unrest in the US drives up the demand and the price.
fair prices can still be subject to price gouging, exclusive dealing, market manipulation, price fixing and other anti-competitive acts. I'm a bit wary of considering what the average guy wants to pay as fair, hes too dumb to know fair if it bit him on the leg. Keeping an eye on dealings between the big players is always a good policy.
