December 23rd is traditionally the day when we all stock up on groceries for the festive period. However, this year the 23rd falls on a Sunday.

The retailers are warning that this is going mean they have to squeeze the busiest shopping day of the year into just six hours - which could bring chaos and carnage to British supermarkets. As a result they have been devising a number of strategies to try to get through in one piece. Sainsbury's solution is being described as a 'lock in'.
