Well, apparently I shouldn't have been so confident that Halcyon did not have an actual resale price maintenance policy - and apparently I also garbled what I meant to write, which was that I thought it "likely" would be a violation of the antitrust laws (not "like be" a violation).
But the reason I thought it wasn't likely is that I doubted that Halcyon truly had an interest in enforcing resale prices through its dealers, and whether such a policy wouldn't really be a case of the dealers *and* the manufacturer agreeing to fix resale prices, with what is truly the dealers' horizontal agreement not to compete on price being enforced through the manufacturer (i.e., not a truly unilateral and vertical pricing policy from the manufacturer). I notice that the policy linked to by whoever answered me earlier referred to an "agreement" between Halcyon, the manufacturer, and Extreme Exposure - which is listed as one of Halcyon's top retailers. I don't do antitrust work, but that still strikes me as a little bit odd. I also noticed that the "policy" was surprisingly vague about what it actually requires.
I was under the impression that these pricing policies had pretty much gone away in the U.S. (I knew there could still be some use of Colgate policies, but thought they would be very rare), and that the DOJ and FTC skepticism about the legitimacy of such policies was the major reason why. Apparently they're still around. Just goes to show you can learn something new every day. Thanks
On edit: I just went back and checked, and the policy doesn't actually use the word "agreement" - this is what I was remembering: "Toward this goal, Halcyon and Extreme Exposure are introducing their Fair Trade Price (FTP) to provide you with an accurate listing of our equipment's retail price. The FTP isn't a bloated MSRP figure that has been inflated to allow for "artificial" discounting. Instead, it is a no hassle, no haggle price that reflects the true quality and value of Halcyon and Extreme Exposure gear."
