A massive Lego Hulkbuster set as seen in Marvel's Infinity Saga got an appropriately huge discount for Prime Day. The 4,000-piece set is just $300 for Prime Day, down from $550. Like Thanos' infamous snap, this eliminates (almost) half the price.

The Hulkbuster set comes with the gigantic Hulkbuster model itself, which stands at more than 20" high once constructed. It also sports light-up Arc Reactors and even has a functioning cockpit that can pair with a sold-separately Iron Man model kit. Like many of the adult-oriented Lego kits, it comes with an information card display and matching minifig of Tony Stark.

The Hulkbuster suit first appeared in the MCU in Avengers: Age of Ultron, as a supersized last-resort suit to fight a raging Hulk if necessary. It was later used by Bruce Banner, aka the Hulk, in Avengers: Infinity War when Bruce briefly lost his ability to transform into his heroic alter-ego.
