I have to say that $30 sounds a bit too steep to me, too. It's probably a reasonable price in some parts of the world, but teachers here in Malaysia would be very unlikely to buy it when they can see similar books in the local shops for about a quarter of the price and they get the chance to browse through it first.

Pricing eBooks is a tricky business, the writer wants a return on the time he invested in writing it. Too low and the price puts people off, too high and the price puts people off, too.
