Thanks for the props - if you are looking at doing any kind of event photography, I can't recommend this system highly enough. Feedback has been unanimously positive from our customers.
The other bonus I didn't mention - the site we pay for handles all the orders/sales tax and everything for us, so we don't even need to worry about it - not having sales tax at all makes accounting much simpler. They handle everything and then cut us a check monthly. We're using shutterfly, but I know there are a number of sites out there doing it.
We link guests to this page,
Storybook Photography, Northern Colorado, from which they can find their event. Feel free to poke around and check it out if you'd like.
My only complaint is that I'd like it if it was branded with our business name throughout the process, but similar services I've seen that offer that functionality are drastically more expensive.
