Digital Version/Access for Convention Purchases?

I picked up a couple of books at PCC over the past weekend from your booth and was wondering if there was a system in place that allows online viewing and the other perks that come when you order from the web store.

Right now we have to do it manually, so if you send an email to store@fakku.net with a picture of your books with the username written on a piece of paper or something, we'll have them added to your account.

Cool, thanks.
