Disappointing if the hard copies bought from other sellers don't include that...
Anyway, there's a coupon code on http://man7.org/tlpi/ that gives 30% off -- that makes the publisher price at least somewhat competitive with other shops.
Currently, the ebook is available only in PDF form and only from No Starch. However, a full range of other ebook formats is currently in production, and when those formats are available they will be sold through the usual retail channels (and made available to No Starch customers who already have the ebook). I expect those other formats to be available around mid-February.
