Not all ticket purchases got you an album. For the purchases that do count you get an album per ticket. You should have received an email with a link last year. They sent another email out this summer once they had a release date and title for the album.
I was moving last year so didn't submit my address waiting to have a stable mailing address. Turns out the link expired and I contacted TM in May but was told, tough luck. Then around June (?) I got an email again with info on the album release date and a new link. Was able to submit the address and now waiting for it to arrive. I purchased 11 tickets last year, for 7 different shows. Only 6 were straight from TM/venue. Only one purchase of 2 tickets through the AMEX presale got me the album. One for me and one for my friend.
Hope this info helps! and hope we get it soon...was kinda hoping it'd ship just a tad early.
