> wouldn't the margin (revenue-costs / revenue) already take into account the cost of acquiring customers? Not necessarily. The word "margin" is very ambiguous because it could relate to many different types of margins. In this case I think its safe to assume that "margin" meant the difference between the customer's price and the direct cost of supplying that particular unit of product, ignoring overheads.
