The promotion is suppose to run from January 1-31, but it appears that LEGO Shop at Home (USA | Canada | UK) has started it early as its now valid online! Spend $75 (or £50 if you are from the UK) and you can get a free LEGO Legends of Chima Ewar’s Acro-Fighter set. Available while supplies last. Thanks to forum member UnknownUser for the heads up.
