Last Chance: Save 30% on Discontinued LEGO Ideas Tree House 21318

LEGO enthusiasts, this is your final opportunity to snag an incredible deal on a highly sought-after LEGO set that has officially been retired. Amazon is currently offering the LEGO Ideas Treehouse 21318 at a discounted price of $174.99, marking a significant 30% off its original $250 list price. It's worth noting that when this set was first released, it was priced at $200; however, LEGO increased the prices of several sets, including this one, in 2022. This current deal brings the price even lower than its initial launch price, a rarity for a discontinued set.

If you're a fan of the LEGO Bonsai kit, consider the Treehouse as its grander counterpart. This set, comprising 3,036 pieces, stands at an impressive 14" x 10" x 9" and weighs over 8 pounds, making it a complex build suited for those aged 16 and above. At first glance, it may appear as just a majestic tree, but there's much more to explore. The base is fully landscaped, featuring a picnic setup beside a buildable stream. The treehouse itself consists of three distinct cabins, each with removable rooftops and intricately decorated interiors. Additionally, a windup crane is included for lifting goods to the treetops. The set comes with both green and yellow leaves, allowing you to switch between seasons at your whim. Embracing the theme of sustainability, all plant and tree elements in this set are crafted from renewable plant-based plastic, moving away from traditional petroleum-based materials.

This deal is a limited-time Amazon Lightning Deal, so it won't last long. It's already sold out at the LEGO Shop and unlikely to return. The LEGO Ideas series stands out for its diverse designs, challenging builds, and impressive scale. The LEGO Treehouse set offers more interactivity than many other display sets, with accessible cabins, a functional crane, and interchangeable foliage. Even at its full retail price, this is a LEGO set I would highly recommend.
