LEGO Mario Kart Bowser's Castle set hits its lowest price ever at Amazon ahead of retirement

The LEGO Super Mario Mario Kart Bowser's Castle set has dropped to $65 at Amazon — its lowest price ever — down from the standard retail price of $99.99. That's a $34.99 saving on a set that's already sold out at the official LEGO store and confirmed for retirement soon.

Set number 72039 packs 1,068 pieces and is rated for ages 9 and up. The finished Bowser's Castle model stands over 10 inches tall, stretches 14 inches wide, and runs 8 inches deep. The build includes Bowser in his Standard ATV and Yoshi in the Mach 8 kart, a castle with foldout walls, a spinning Fire Bar, a platform on top for Bowser to stand on, shell-launching karts, and even a small banana figure you can place on the track.

LEGO's Super Mario line has been running since 2020 and blends physical building with app-connected interactive figures. Sets in the line rotate out regularly, and once a set hits retirement it typically disappears from shelves fast — secondary market prices on retired LEGO sets tend to climb quickly after that point.

If the Mario Kart theme appeals, Walmart's ongoing Bricktember sale also has a deal on the Luigi and Mach 8 set right now. Given the retirement timeline and the sold-out status at LEGO's own store, waiting on this Amazon price is a gamble not worth taking.
