I should add that the milk and biscuits/cookies are an American import. Note: yes, it's summer here.
There's also a cute series of short ads about a man called Noel who might be Santa working at New World supermarket:
New World Christmas
It must be Christmas (we don't drink milk like Americans do so that's why the stares)
Santa stocks up on carrots
Are you Santa?
