For most distributors it won't be worth the risk to drop below the minimum price they are allowed to sell for. Of course there are other ways for them to drop the price if you're a really good customer, by offering free or deep discount on accessories or a different game (recently got a quote for three new pinball machines and an air hockey table) so they could deeply discount the air hockey table that doesn't have the same price restrictions if I was going to be spending $20,000+
