My step sister tells her children that all christmas presents come from Father Christmas. So she takes off any labels that are attached to the presents so that the children don't know they have come from someone else. She lives abroad so I have to post the presents, otherwise I'd hand them to the children themselves. Now, I know that it's her family's tradition. But a little bit of me feels like not bothering to get nice presents as the children don't know that I've gone to the effort.
