Don't miss these 12 best Prime Day Lego deals on some of my favorite sets, because time is almost up

1. Lego Disney Young Simba The Lion King | $129.99 $64.39 at Amazon
Save $65 - This reduction took me by surprise, and that doesn't happen often. We've never seen the larger, more detailed (and arguably better, if you ask me) Simba kit for less than it is here in honor of Prime Day. I managed to see it at the London Toy Fair in early 2025 before it was announced, and was instantly smitten with this kitten.

Buy it if:
✅ You wanna be a mighty king...
✅ ...like no one was before

Don't buy it if:
❌ You're happy with the cheaper model

Price check:
💲 Walmart | $64.39

2. Lego Grogu with Hover Pram | $99.99 $84.43 at Amazon
Save $13 - This Prime Day really has been about the cute Lego sets, as we have another adorable one hitting a record low price for the event. My price-matching software says it doesn't venture much below MSRP on average, which makes this an absolute steal.

Buy it if:
✅ You adore Baby Yoda and want one for yourself
✅ You're hunting down the perfect gift

Don't buy it if:
❌ You already have an older Lego Grogu

Price check:
💲 Walmart | $99.95

3. Lego Star Wars Imperial Star Destroyer | $159.99 $111.99 at Amazon
Save $48 - It may not be a record low price, but the fact that we haven't seen this kit get much in the way of a discount before now brings the Star Destroyer out of hyperspace and onto this list. Fans have eagerly awaited a price cut for this detailed yet reasonably-sized model, so it's getting a nod from me here.

Buy it if:
✅ You collect midi-ships
✅ You're looking for a display piece OR kids' playset

Don't buy it if:
❌ You have the old UCS version

Price check:
💲 Walmart | $165.90

4. Lego Star Wars R2-D2 | $99.99 $79.99 at Amazon
Save $20 - Because this new version of everyone's favorite astromech has only ever been five cents less, I'd say it's one of the stronger Prime Day Lego set discounts so far. Seeing as it's amongst our favorite Lego kits of the past year (as mentioned in our Lego R2-D2 review), I wouldn't sleep on this one.

Buy it if:
✅ You want an iconic but reasonably-sized set
✅ You'll be getting C-3PO as well

Don't buy it if:
❌ You have the older, larger version

Price check:
💲 Walmart | $79.99

5. Lego Star Wars C-3PO | $139.99 $111.95 at Amazon
Save $28 - The R2 listed above was built in the right scale to go perfectly with the new C-3PO, and as luck would have it, that kit just got a massive reduction as well. Thank the Maker! This model hasn't ever been cheaper, and as we say in our Lego C-3PO review, it's definitely worth a look if you love display pieces.

Buy it if:
✅ You want a detailed set for show
✅ You're buying R2 as well

Don't buy it if:
❌ You're buying a playset for kids

Price check:
💲 Best Buy | $139.99

6. Lego Star Wars Millennium Falcon | $84.99 $67.99 at Amazon
Save $17 - And here's another record-low price to keep things spicy in the world of Prime Day Lego set deals. Sure, there are bigger and more complex versions of the galaxy's fastest hunk o' junk. But as I point out in my Lego Millennium Falcon review), this is arguably best for most people thanks to its size, detail, and affordability. It doesn't usually drop below $74 either, so is a bargain to boot.

Buy it if:
✅ You'd like an iconic part of Star Wars history
✅ You don't have space for the big versions

Don't buy it if:
❌ You'd prefer the larger, more detailed versions

Price check:
💲 Walmart | $67.98

1. Lego Rivendell | £429.99 £365 at Amazon
Save £65 - If you ask me, this is hands down the best Lego set I've ever seen or made (which is why it got a five-star score in my Lego Rivendell review). While that isn't a record low price, it's not far off, and the kit usually averages between £401 and £410 in cost anyway.

Buy it if:
✅ You want a magnificent centerpiece
✅ You adore all things Lord of the Rings

Don't buy it if:
❌ You don't have much room to display it

Price check:
💲 Lego | £429.99

2. Lego Barad-dur | £399.99 £339.98 at Amazon
Save £60 - Sound the 'record low price' alarm, because we've got one! I've never really seen this model drop in price much, and its batting average cost is anywhere between £390 and £399.

Buy it if:
✅ You prefer more complex builds
✅ You're building a Middle-earth collection

Don't buy it if:
❌ You don't have much room to put it on display

Price check:
💲 Lego | £399.99

3. Lego Great Deku Tree | £259.99 £212.40 at Amazon
Save £47.59 - I am a huge Legend of Zelda fan, so this kit was one of my most anticipated releases of the past year (and it still is now that I'm building it myself). I've not seen such a big price cut on it before now, and the average cost is around £246.

Buy it if:
✅ You adore the Legend of Zelda series
✅ You love Breath of the Wild/Ocarina of Time

Don't buy it if:
❌ You aren't a BotW/OoT fan

Price check:
💲 £259.99 at Lego

4. Lego Harry Potter Book Nook | £89.99 £79.99 at Amazon
Save £10 - I think the new Book Nook range is one of the best things Lego has done for ages, and this Hogwarts Express version is the most appealing of them in my eyes. It's never been available for less, so jump on that Prime Day bargain if you want it for your own shelf.

Buy it if:
✅ You'd like to add magic to your bookshelf
✅ You want a detailed, intricate scene

Don't buy it if:
❌ You'd rather save for the Hogwarts castle

Price check:
💲 Wayland Games | £80.99

5. Lego Star Wars C-3PO | £124.99 £84.90 at Amazon
Save £35 - What's that? Another record low price? Yep, the anxious protocol droid has tumbled to his cheapest ever point as part of Amazon's Lego sets discount, and I can't say I'm mad. It's a great kit and goes brilliantly with the new R2 model.

Buy it if:
✅ Your favorites were always the droids
✅ You have R2 already, or will get him soon

Don't buy it if:
❌ You're hoping for a kids' playset

Price check:
💲 John Lewis | £91.99

6. Lego Lord of the Rings Book Nook | £109.99 £93.49 at Amazon
Save £16 - Go back to the shadow... but not before you check out this eyebrow-raising price cut that brings the Balrog Book Nook to its cheapest ever point. It's rare to see Lego sets so discounted just after launch, which means this Prime Day saving is even better.

Buy it if:
✅ You'd like to bring drama to your bookshelf
✅ The Lord of the Rings is your favorite

Don't buy it if:
❌ You want a more detailed model

Price check:
💲 Wayland Games | £98.99
