When is the best time to order from Taobao?

[milk-tea-bunny.livejournal.com]

So Christmas time is coming up and I may ask my boyfriend for something from the Taobao shops. Then again, I might wait until after Christmas to order something. However, I'm aware of the long Chinese holidays before and after the holidays. My question is; when is the best time to order from Taobao? Possibly, in a small list of sorts, of when is the best time to order throughout the year.
