I've reviewed Lego for years, and these are my favorite Prime Day deals so far

You might not associate Prime Day with Lego, and that's fair enough. The sale is better known for its tech discounts. However, it also has a habit of throwing out Lego discounts like they're confetti. 

Despite all the odds, these are actually decent. I've been covering Lego and sales such as Prime Day for more than five years now, and the bricks from Billund consistently rank amongst the best offers. Even during lean times where the savings aren't as tempting as they could (or should) be, tempting price cuts on the best Lego sets can be relied upon. 

2024 isn't any different. Lego Harry Potter has been doing particularly well this time around; the Hogwarts Castle and Grounds kit has dropped to a record low price of $135.95 at Amazon instead of $170, for example. Meanwhile, one of my favorite Mario sets - the Piranha Plant - is $47.95 at Amazon rather than $60. 

Even competing retailers are getting in on this month's Prime Day Lego deals. As a case in point, the adorable new Stitch model is $51.95 at Walmart (down from $65).

Anyway, to business: here are the offers that've stood out to me personally. If you're hunting down the best deals, I'd argue that these take the cake.
