ASM Printed & Electronic Bundle Purchase

Sorry, this is probably a ridiculous question but I just wanted to confirm before making a purchase of $340.

Has anyone purchased this bundle? I get immediate electronic access & receive the hard copy several days later? I am confused on the 30% printing part. What does that mean? If I am already getting a hard copy shipped to me, why would I want to print any percentage of it? That's why I am worried about purchasing this since if I do not receive a 100% printed copy in the bundle then I rather just purchase the hard copy version for $250.
Thanks!
