I'm very confused!

I just found a code to get an additional 15% off the photopass CD, taking it down to $84.95 so I ordered it.

What confuses me is that my receipt says I pre-ordered the CD, but it also says it will soon be shipped and I'll get an email at the time of shipment.

I can't believe they would send me a blank CD but this receipt is extremely confusing. I thought I came home from vacation, entered my photopass IDs and then had to upload them?

I've never done this and could sure use some expert help!

Thanks in advance for any advice.
