Certified Oakley dealers can't discount their glasses without getting permission from Oakley. They have a set price that their glasses can retail at, and if you go lower then that price, Oakley will pull their merchandise from the store. Unless they are discontinued models.
Oakley needs a governmental price-fixing lawsuit against them. Those tactics are made to circumvent capitalism. Nintendo was guilty of this once because they threatened to quit selling merchandise to stores that did not charge high enough prices.
