I had bought an eBook sometime in the past from the Cool-ER eBooks shop, so I guess I got on their mailing list. I received this e-mail today, which may be of interest.
I know there's a couple of Sony format copies of Peter Pan on MR already. But there seems to be some kind of free offer at Cool-ER books at the moment for people to download an eBook (PDF) and Audio Book format of J.M. Barrie's Peter Pan.
Here is the promo page link:

The catch is they want your e-mail address, as they send you the download link to get both formats of the book. So I guess you may get promos from them in the future, but you can choose not to receive them when you first give them you e-mail.
I have no idea how this format compares with the others offered on MR, but it's free so enjoy!
