Why did Wizards of Waverly Place never have a Christmas episode?

I was just thinking about how there was never a Christmas episode of Wizards of Waverly Place. Most Disney Channel shows have Christmas episodes. There were a few shows that didn’t have Christmas episodes like Jonas and Cory in the House. But I think Wizards of Waverly Place is the biggest show that doesn’t have a Christmas episode. I think a Christmas episode of Wizards of Waverly Place would have been a good episode. Maybe they weren’t able to come up with a good story for a Wizards of Waverly Place Christmas episode, or maybe they thought a Christmas episode wouldn’t really fit in with Wizards of Waverly Place. I don’t know, but what do you think? Why was there never a Christmas episode of Wizards of Waverly Place?
