Whether you’re looking for some inspiration to keep the kids busy this summer, need to stash away a few evergreen birthday party presents, or want to get a head start on your holiday shopping list—Amazon Prime Day is your chance to score big brands at great prices.

The only real issue with a Lego habit is that it gets expensive fast, no matter if you are trying to recreate the entirety of Middle Earth with supersized Lord of the Rings sets, or kitting out your model Formula 1 racing team at home.

Amazon Prime Day 2025 is on, and there are opportunities to score all-time low prices on a wide variety of LEGO sets that include 30% off the LEGO Star Wars Imperial Star Destroyer (75394) and the LEGO Icons Boutique Hotel (10297).

Mighty Bowser isn't the only set currently on sale for Amazon Prime Day. Check out these other adult-themed sets from Walmart, Amazon, and even the LEGO Shop, including the Milk Way Galaxy, the LEGO Technic BMW M 1000 RR Motorcycle or the LEGO Icons Land Rover Classic Defender 90, which is expected to be retired later this year.

Save yourself some serious Galleons with £100 off the sprawling 6,020-piece Lego Harry Potter Hogwarts Castle with one of the best Amazon Prime Day Lego deals we've seen so far
