HarperCollins seems to be having problems with its ebook pricing. On one site, newly released hardbacks with ebook have the ebook with a lower list price than the hardback, but when you go to buy, the ebook is shown with the hardback's list price.
I'd guess that somewhere the hardback price is being used instead of the ebook price. Hopefully they'll sort it out soon.
Some examples:

Of course, their ebook prices are still a bit high for my liking, but it seems they are currently trying to charge even more than
they think the ebooks are worth!
