If you do a search for 'christmas' on Walmarts site you get a page titled "Holidays". However you also see this:
We've brought you to our "Holiday " page based on your search.
Not what you're looking for? View a list of items that match your search for "christmas".
When you click there you get a listing for 7970 items. The other searches come directly to Kwanzaa or Hanukkah. Don't know why the difference there, but the Christmas link is available.
As far as the email, I honestly can't see that coming from a Walmart corporate office either. It just doesn't seem like something a huge company would say. I wonder if it's a creation of that one particular person like some email responses that folks have received in the past from various companies.
Since Christmas IS a holiday, I don't see what the problem is.
HOLYday. Holy,,,,,, different, set apart from others.
Now that you have actually gone to the WallyWorld website and searched for "Christmas" you may want to scan your computer for the nasty cookies, adware, and spyware that Wallyworld left on your computer.
