Just remembered this Philip Greenspun chapter against selling packaged software.
Meanwhile I'm arguing with Umair that price can never carry meaningful information about information products.
Perhaps a better way of putting my point is this. Price is a single scalar value. But needs to carry more than one piece of information. Even with scarce resources, price reflects business model as well as value and demand for a product. For example, if my strategy is to give away razors and sell razor-blades, the price of the razor doesn't accurately reflect the cost of manufacture or the quality. That information is swamped by the information that this is a loss-leader.
But at least there are some constraints on price from material costs, and demand. In the case of information products, the constraints are much weakened, particularly the constraint that if X has the thing, then Y can't have it.
What this means is that the space of possible business models or institutional logics which determine the price is far greater than for non-scarce resources. Information sellers have a lot of freedom to experiment with different structures, bundling and unbundling etc. And the meaningful information about demand or quality which you can derive from the price is much lower.
