It is the thought that counts.
When people are totally snowed-under (figuratively speaking in the southern hemisphere, at least) by an avalanche of last minute events/deadlines/relatives/to-do lists it’s nice to think that someone else is wishing them a happy holiday season. So, they can take off for the bach or the camping ground, flick out their beach towel, and put on their jandals with a light heart and a spring in their step. Knowing that Santa has already been. (No chimney, or Christmas cake and glass of milk, required.)
