Remember walking down the aisles of Toys “R” Us, pleading with your parents for the latest LEGO set? And they responded with something along the lines of: “You already have too many at home.” Well, now you’re an adult — at least you should be if you’re reading Rolling Stone, which means you’ve got adult money. And guess what? You get to decide how many LEGO sets are too many. (Spoiler: there’s no such thing.)
Right now, you can treat yourself to a new LEGO set for up to 30% off during Amazon’s October Prime Day (or days, more like it, the event runs from Oct. 7 to 8, 2025). You read that right. Typically, LEGO kits can run from $25 for smaller builds to well over $100 for the large, intricate ones (the most expensive set ever sold for $10,000). But we’ve found deals ranging from just $10 to $150, leaving room in your budget for whatever else your grown-up heart desires.

This year’s best LEGO deals include everything from Disney classics — like Stitch from Lilo & Stitch —to botanical flowers, iconic city skylines, and popular fandoms. Most of these kits are designed for adults (ages 18 and above), but there are plenty of options for builders of all experience levels.
If you’re new to LEGO, there’s never been a better time to start. A recent article published by the National Institute for Play highlighted the mental health and cognitive benefits that playful activities, such as building toys and entertaining yourself with board games, can provide. “Engaging in playful activities helps adults cope with stress and enhances mood,” the article states. It can also “trigger the release of endorphins, reducing cortisol levels, and fostering relaxation,” it continues. In short, play isn’t just for kids; it’s good for your mental well-being, too.

Beyond the positive mental effects LEGO can have, they’re also a great keepsake to display once your masterpiece is complete — whether it’s on your desk, bookshelf, or even inside one of those special coffee tables designed to showcase your pièce de résistance. You can check out some of these options during Amazon’s Prime Day deals.
And let’s be honest — at the end of the day, building LEGO sets is just plain fun. You don’t need a reason beyond the joy (and dopamine boost) that comes from snapping those bricks together. So go ahead — grab your favorite LEGO sets on sale during Amazon’s Prime Day while they’re still in stock, and spend your adult money wisely. Pay your bills, of course — but don’t forget to invest in a little happiness, too.
