I know they send out an email to let you know when they are having it..

Unfortunately, last year people complained that they recieved the email after the sale ended.
It might be worth checking the website every day from 20th Dec, to 30th Dec, so you catch the sale on the day it occurs (seeing as it not normally a specific day around Christmas that they have the sale (it has been early January a few times as well)).
