Publix is making December birthdays extra jolly this Christmas. See the grocer's new Christmas ad and "Merry Birthday" cake.

Is it even a party without cake? Yeah... we don't think so either. But it's hard to know just how much cake you're going to need. Some people aren't cake eaters at all, while others want all the cake.
