If you've still got your battered iPhone there's an app available. With this you can scan the stickers and it adds them to your total or add them manually. It also makes lists of what you've got and what you need.
Oh, I am so into it. Was so proud yesterday to see my daughter (she is six) placing all those stickers alone... But I am there to enjoy it even more, of course...
