Amazon Prime Day is here, and some of the best discounts on premium LEGO sets for adults are already hitting rock-bottom prices. With the event running only until June 26, high-demand items are selling out at a record pace.

Key highlights include significant price cuts on the LEGO Super Mario Piranha Plant, the Star Wars Imperial Star Destroyer, and the LEGO Icons Bumblebee. Many of these sets are slated for retirement in July, meaning once these Prime Day deals sell out, they may be gone for good.
