Because TLPI was temporarily out of stock while the second print run was being completed, No Starch Press has further extended their earlier discount offer, allowing you to order the paper version of TLPI from them at a 30% discount (i.e., a total price of US$70 plus shipping), and receive the ebook free (look here for details on the ebook release). The offer is now extended to 30 June 2011.
To obtain the discount (and ebook), you must buy TLPI direct from the publisher's web site, and quote the coupon code Mamaku (what's that?). (No Starch Press is located in San Francisco, so international shipping rates will apply for readers outside North America.)
No Starch Press has the second print run in stock, so they can ship immediately.
