Christmas shopping
From Tardis Wiki, the free Doctor Who reference
In preparation for Christmas, Christmas shopping was shopping for Christmas presents. Before the holiday, Oxford Street in London was full of people battling over who'd get what. (PROSE: Christmas Special) It so busy on Oxford Street a week before Christmas that one could barely move. (PROSE: History 101)
In 1998, the time-active children's toy Parablox was released during the Christmas shopping season. The Great Houses excised it from the timeline shortly after Christmas. (PROSE: The Book of the War)
