Amazon's Prime Big Deal Days (Oct. 7-8) are here! It's the unofficial starting gun for the holiday shopping season, and that means it's time to talk about one of the most bulletproof gifts you can buy: Lego. Whether you're shopping for a kid who wants a cool Star Wars ship or an adult who'd love a botanical set for their desk, there's a good chance a Lego kit is on someone's list.
But before you start adding every discounted set to your cart, here's a pro tip for shopping on Amazon: a "deal" isn't always a deal. Some Lego sets have a sale price that's actually been the standard price for weeks or even months. A true Prime Day deal is a price drop that's new and noteworthy.
We've done that homework for you. This list has been vetted against price histories to filter out the fake sales. The deals below represent actual, limited-time discounts on some of our favorite Lego sets.

Why we like it
Lego Advent calendars are a holiday classic, and Prime Day is the perfect time to grab one before the December rush. This Star Wars-themed calendar is at its lowest price ever, making it a great time to buy.
Behind the 24 doors, you'll find a bunch of characters and mini-builds perfect for any fan of the franchise, including C-3PO, a Holiday Jawa minifigure, a Babu Frik figure, alongside five Lego droid figures: R7-A7, BD-72, a Scrap Battle Droid, BB-8 dressed as a snowman, and a Super Battle Droid.
