Presale question re: CD purchase

[EveryHour]

(Sorry if this has already been discussed within another thread...)

If someone who has already done a presale can verify how the CD purchase works, I'd really appreciate it. (My presale is nearing and I'm getting nervous!) Do I pre-order the CD from Lindsey's website at any time before my presale after which I am given a code to use, or is it the type where I select to purchase the CD on Ticketmaster right when the tickets go onsale? I know the website messages explain it fairly well, but I just want to be sure.

Thanks!
