However, customers can still post Special Delivery Saturday Guaranteed items by December 23.
Special delivery is for important documents or items of value.

Each year Royal Mail invests in additional resources for its Christmas operation to handle the festive mail bag.
This has included recruiting 19,000 seasonal workers and opening nine temporary parcel sort centres.
