Catherine is right...you'll get another e-mail with your pre-order code. Then after you get all of your pictures loaded and edited, you purchase your CD. You'll enter the code that was e-mailed to you on the payment screen. I also used the 15% code. I just ordered my CD yesterday and there was a $7.00 charge for shipping just so you are aware!

I also saw where the price of the photopass CD is going up to $149 on (I think) 6/16...so if you are going soon, I would get the preorder price!
