Amazon Prime Day is generally one of the best times to buy LEGO sets at a discount and 2026 is certainly continuing that trend. If you’re looking for deals on some of the more expensive builds for adults, there’s already a ton of worthy price drops on 18+ sets for you to browse online.
Prime Day doesn’t officially kick off until midnight tonight, but Amazon and various other retailers have already started dropping some of the best LEGO deals of the year. The sales event is set to run until June 26 this year, so expect early deals to sell out before then.
The Best Prime Day LEGO Deals for Adults Today
Editor’s Note: We’ll be regularly updating this list of LEGO deals with new discounts and stock updates. If something goes out of stock during the sale we’ll note it in the product card.
Target’s LEGO sale went live over the weekend and dropped some of the best LEGO Super Mario deals of 2026 so far. Among these offerings my overall favorite is the LEGO Piranha plant. This is actually the first LEGO set I bought for myself as an adult and it has since put me on a journey of brick-building rediscovery. There’s also the Super Mario World: Mario & Yoshi set on sale, which our LEGO Editor Chris Reed has called his “favorite Nintendo set to date”.

If you’re looking for something you could easily incorporate into your shelf, there’s also the Hogwarts Express book nook deal. This is one of the first book nook sets released last year and has dropped down to its lowest price ever for Prime Day. It can easily fold up to work like a traditional book nook or you can disconnect the set in the middle and use it as a pair of bookends.
For any of you Transformers fans out there, I’d also note the LEGO Bumblebee set is on sale now. It’s not at the lowest price we’ve ever seen, but the set is currently set to retire at the end of July. There are only actually three LEGO Transformers sets you can even buy, so it’s possible this deal could result in the set going completely out of stock before the end of Prime Day. We’ve had the chance to build this set and it’s as cool as you think it is since it actually transforms.

Last but not least, Walmart is currently offering a discount on a very recently released LEGO soccer ball set. The soccer ball set was officially released back in March alongside a Fifa World Cup build. It’s designed like a Technic set to be perfectly round and includes a mechanism to open the ball to a little scene on the inside. This discount was originally only available as a Walmart+ Early Access deal, but now anyone is able to buy.
A ton of LEGO sets are retiring next month
LEGO is currently poised to retire a bunch of popular sets on July 31. This means that every retailer likely has a limited amount of stock on any of those sets. We’ve already seen the Legend of Zelda Great Deku tree set go completely out of stock everywhere without any sort of discount attached, so expect more sets to disappear before their actual retirement date.
