Prime Day has taken up to 36% off LEGO building sets, with limited stock running low and starting from $7

36% off From $7

As part of its Prime Big Deal Days event, Amazon is taking up to 36% off a small selection of LEGO building sets. Most of the sets we’ve seen since the sale went live at midnight have been lightning deals and sold out within the first handful of hours, but there’s still some nice finds that have stock left here, like the LEGO Super Mario Dry Bowser Castle Battle expansion set for $77 shipped. Normally sitting at a $110 price tag, this building set spent the last year at its MSRP since releasing back in August 2023, with mid-June 2024 seeing the first discounts rolling in, with July seeing the lowest price of $97. Today you can grab it at an even bigger price cut of 30% giving you the best price we have tracked.

Stacking up to 1,321 pieces, this spooky build assembles an alternative form of Bowser’s Castle based on the iteration of the villain that first appeared in the New Super Mario Bros video game after the king of the Koopas falls into the lava defeated, only to rise again to challenge his foes to another round. It comes packed with all sorts of other enemies too, like the bone Piranha Plant and a bone Goomba. You’ll of course be getting Dry Bowser as well – plus, Purple Toad too, who has been captured and held prisoner, waiting for heroes to rescue him.
