So I go and say that the Boxing Day sales can be a bit disappointing and then immediately discover a decent LEGO Boxing Day offer.
Online right now or in-store Boxing Day you can get 20% off LEGO at David Jones. Unfortunately this offer excludes all Creator sets. If you are buying online note that the discount is applied in your shopping bag not the product page.
This sale actually runs until January 8th 2017 so fingers crossed you’ll be able to get some 2017 sets on sale.
