Attention all LEGO enthusiasts! This is your final opportunity to grab a fantastic deal on a retired LEGO set. Amazon is currently offering the LEGO Ideas Treehouse 21318 at a steep 30% discount, bringing the price down to $174.99 from its original $250 list price. This is particularly noteworthy because, although the set was initially priced at $200 upon its release, LEGO increased the price to $250 in 2022. Snagging this deal means you're getting it for less than the launch price, which is rare for a discontinued set.

If you're a fan of the LEGO Bonsai kit, consider the Treehouse as its grander counterpart. This set boasts 3,036 pieces, resulting in a model that measures an impressive 14" x 10" x 9" and weighs over 8 pounds. Designed for builders aged 16 and up, this set offers a complex build experience. At first, you'll see a majestic tree, but look closer and you'll discover a detailed landscape with a picnic setup by a buildable stream. The treehouse features three separate cabins, each with removable rooftops and fully decorated interiors. There's also a windup crane for hauling goods to the treetops. To enhance the seasonal aspect, the set includes both green and yellow leaves. Committed to sustainability, all the plant and tree elements are crafted from renewable plant-based plastic, rather than petroleum-based plastic.
This offer is part of a limited-time Amazon Lightning Deal, so it won't last long. It's already sold out at the LEGO Shop and is unlikely to return. The LEGO Ideas series is renowned for its varied designs, complex builds, and impressive scale. The Treehouse stands out with its interactivity, featuring accessible cabins, a functioning crane, and swappable foliage. Even at full price, this set would have been a top recommendation.
