Interesting, we don't have a specific day for Christmas sales here, well maybe Boxing Day or the Day after Boxing Day *depending on which state you live in). Our November holidays (Armistice Day & Melbourne Cup) just don't lend themselves to shopping...
But isn't tomorrow awfully late to start Christmas shopping? Retailers her have been at it for weeks already... At least mid-October. Spring here has no real holidays. Nothing retailable in October or September (except Father's Day) either.
