For what it's worth I work at a large multi-national company and have gone through antitrust training a couple of times. Even if the competitor is being "helpful", any discussion among competitors of pricing in the market violates antitrust law. Also, even if the results of the discussion would ultimately benefit consumers (such as "let's lower our price to x to move units"), this is still illegal. Bottom line, never engage in ANY discussions with competitors over price no matter what.
