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.

I review Lego sets for a living and these are the 10 best Lego Star Wars sets released in 2025 so far— you might even find them discounted during Prime Day.

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).
