I spend a lot of time browsing Amazon. Job hazard I suppose. It’s getting harder and harder to find LEGO sets at low prices. I used to be able to post lists of sets under $10 but that is few and far between right now. But I did spot some regularly $20 sets from The LEGO Movie 2 for under $15! Some of these are discontinued so this might be your last chance to buy them!
LEGO THE LEGO MOVIE 2 Systar Party Crew 70848 Building Kit (196 Pieces) – $13.79 (save over $6!)
LEGO The LEGO Movie 2 Emmet’s Thricycle! 70823 Three-Wheel Toy Building Kit for Kids (173 Pieces) (Discontinued by Manufacturer) – $14.99
Amazon stock and pricing can change rapidly so order quickly if you see a deal on something you want!
