One of the more impressive and enduring LEGO sets for adults (well, ages 16+, anyway) is the LEGO Ideas Tree House. It's a massive three-unit tree house you can build with either green leaves or yellow leaves for an autumnal feel. It normally rings in at $250, but it's on sale for $75 off for Prime Day. Grab it before it's gone.

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).

It doesn’t take wizardry or special spells to see how good this Amazon Prime Day deal is, especially if you have Harry Potter fans ages 8 and up in the house. The LEGO Harry Potter Hogwarts Express & Hogsmeade Station is 34% off for Prime Day, bringing the price of this fun playable model with 9 minifigures down to just $86.

But we’ve got some good news – we’re currently in the midst of the Amazon Prime Day sale which always comes through with a strong selection of deals across all of the key collaborations, from Harry Potter to Star Wars to Lord of the Rings,
