From the white paper:

Imagine for a moment that a spammer promoting penile enlargement pills for $29.95 a bottle sends out ten million spams - a very moderate number by modern standards. If the spammer gets one thousandth of one percent sales response (.001%), he will sell 10,000 bottles, for a total return of $299,500.00. Even on response rates as small as one millionth of one percent, operations like this can still turn a profit that makes them worthwhile, simply because of the enormous number of addresses that can be reached at almost no cost.

Last time I checked 0.001% of 10^7 was 100, not 10,000. The spammer would sell 100 bottles for a total return of $2,950, not a huge haul.

At one one millionth of a percent response, he would sell on average one tenth of a bottle.
