If you somehow still don’t have the LEGO Ideas Pop-up Book (21315), Amazon has it on sale for a price that probably won’t be beaten in the near future. It is priced at $49.99 which is 29% off and is the second to lowest price it’s been at since the beginning of July for a few days. It’s rumored that this set will be retiring pretty soon especially since Central Perk (21319) will be coming out next month.
