Wonderfully said! Even with the book case (h/t phonon's link above), AMZN was still making money in the aggregate in its e-book business, despite the loss-leader bestsellers being sold at $9.99 and below their wholesale price. That's starkly different than firms (e.g. industrial) over-producing, under-pricing, and losing money (in aggregate) to gain market-share.
