I keep seeing the term "price fixing" getting thrown around. Pretty sure this doesn't qualify as price fixing, which is illegal. I am in the U.S. so I am speaking of my country.
This seems to be a case of a manufacturer imposed minimum price which is not a violation of U.S. law, not sure about France.
From the FTC website:
"If a manufacturer, on its own, adopts a policy regarding a desired level of prices, the law allows the manufacturer to deal only with retailers who agree to that policy. A manufacturer also may stop dealing with a retailer that does not follow its resale price policy. That is, a manufacturer can implement a dealer policy on a "take it or leave it" basis."
"The critical distinction is between a unilateral decision to impose a restraint (lawful) and a collective agreement among competitors to do the same (unlawful)."
This seems to state that manufacturers can set minimum and maximum prices as long as they are enforced across the board.
The full text of the FTC rule can be found here.
