Amazon Prime Day is providing considerable discounts on LEGO sets, particularly those geared towards adult builders. Many of these 18+ sets are seeing notable price reductions, though some have already sold out as the sale event progresses. The sale is scheduled to continue until Friday, June 26.

Several high-profile sets have already reached a sold-out status, including the LEGO Technic Peugeot Hypercar, LEGO Technic Liebherr Crawler Crane, and LEGO Icons Fountain Garden. Retailers like Target have also contributed to the LEGO deals, offering discounts on Super Mario sets. Among these, the LEGO Piranha Plant is highlighted, alongside the Super Mario World: Mario & Yoshi set, which has been praised by IGN's LEGO Editor.

For Star Wars enthusiasts, the Imperial Star Destroyer is available at its lowest price of the year and includes a Cal Kestis minifigure. Another notable deal is on the Hogwarts Express book nook set, which has dropped to an all-time low price for Prime Day. This set can function as a traditional book nook or be separated into a pair of bookends.

Transformers fans can find the LEGO Bumblebee set on sale. While not at its absolute lowest price historically, this set is slated for retirement at the end of July, making it a potentially limited-time purchase opportunity. It is one of only three LEGO Transformers sets currently available and transforms as part of its design.

Walmart is also offering a discount on the recently released LEGO soccer ball set, which launched in March alongside a FIFA World Cup build. This Technic-style set is designed to be perfectly spherical and features an opening mechanism revealing an interior scene. Initially an exclusive Walmart+ early access deal, it is now available to all customers.

A significant number of LEGO sets are scheduled for retirement on July 31, meaning stock for these items is limited across all retailers. The Legend of Zelda Great Deku Tree set has already sold out without any discounts, indicating that other popular retiring sets may also disappear quickly, especially as sales events continue.
