Disappointingly (or not, depending on your viewpoint) there will be no M&S beauty advent calendar this year. There will be a Beauty Edit of 10 items apparently according to this link I found

DH has bought me the advent calendar as a treat for the last couple of years - perhaps I'll tell him he can buy me the Liberty one instead....!
