please, does anyone know when all the sales begin?

[HoHoHappyHolidays]

I really need to revamp my wardrobe but have no idea when the sales begin :( does anyone please have a list of dates of when sales begin.

TIA :)

I sign up with the shops that I like and they send me an email to let me know when their sales are starting, or 'like' them on Facebook and they will send you a notification.

John Lewis online sale starts at 5pm on 24 December .

A lot of them have started already ...
