I'm a little confused about the physical vs download as well.
On the CD redemption screen, you can choose how many CDs you want (it defaulted to 2 for me). I changed it to 1 so I could use the other for a download - based on the wording on ticketmaster, I believe we will receive another email after/on Dec 1 to let us redeem for a download.
But, after submitting my redemption for one CD, I was shown a screen to SHARE WITH A FRIEND where I can enter an email address. It says, "You can share this album with 1 friend."
Is this the option to download - i.e. will it send a download
