Some modern sets have very short life spans, as will be the case with The LEGO Movie 2: The Second Part 70840 Welcome to Apocalypseburg! (review). The 3,178 piece set is on a list of sets expected to retire this year that has been shared by The Brick Fan. Those looking to own the impressive centrepiece model should consider placing an order before it is discontinued.
Many other sets in the theme will also be retiring, most of which are currently available at a discount:
70820 LEGO Movie Maker
70823 Emmet’s Thricycle!
70824 Introducing Queen Watevra Wa’Nabi
70825 Queen Watevra Wa’Nabi’s Build Whatever Box!
70828 Pop-Up Party Bus
70829 Emmet and Lucy’s Escape Buggy
70835 Rex’s Rexplorer
70837 Shimmer & Shine Sparkle Spa
70838 Queen Watevra’s ‘So-Not-Evil’ Space Palace
Bear in mind that this list is reported in good faith, there is always the possibility that some sets may sell out sooner or may stay in stock longer than expected. It is a useful guide though for those debating what sets to purchase during the remainder of 2019.
