Several Lego sets are getting generous discounts for Cyber Monday, including the sprawling Harry Potter Hogwarts Castle Set. The massive set consists of 2,660 pieces--and it’s currently available for its lowest price ever. Both Amazon and Walmart are offering discounts, so if one retailer sells out, be sure to check the other.

Yep, in case you missed it, Amazon’s Cyber Monday Sales Event is underway, and the e-tailer also announced that there will be extended savings through December 3 with 12 Days of Deals. (Exciting news, of course, but heads up: We can’t guarantee that popular discounted Lego sets won’t sell out before the end of Cyber Monday!)

Black Friday isn’t the only time of the year to score the biggest savings on Lego sets. Cyber Monday deals offer one final chance to save money and snag the ultimate gift for the creator in your life.
