You don't even have to believe in the Christmas story to have the ads want to make you scream... it really is all about Love = Spending Money.
(The ads that have the happy Polar bears and penguins frolicking together just make me grit my teeth because of the geographical illiteracy involved! Plus, I suspect if they really were on the same continent, those bears would be eating those penguins...

We seem to have a lot of displays on people's lawns this year with "North Pole" signs, Santa Claus... and penguins. Okaaaay...)
