When I went to the Manning website it offered two combo deals. 1) $49.99 -- pBook + eBook + liveBook
2) $39.99 -- pdf + ePub + kindle + liveBook Using the 50% off discount code gave: 1) $49.99 - $25.00 = $24.99; 2) $39.99 - $20.00 = $19.99 I assumed the pBook in combo 1) was for the print version, while it's not included in combo 2). Is this correct? I went ahead and got combo 2) anyway (Save the Trees!). Best to open an account to get access to more than one download of the electronic versions if needed.
