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.

Ask anyone that comes round to my home, and they'll tell you my LEGO addiction is out of control. What started as a new set of plastic bricks every now and then, has become an ever-growing collection that takes up all the space on my bookshelves and table tops.

Usually priced at £410, you can pick it up in the Black Friday sales for just £307 — a 25% saving, and more £103 off the usual asking price. From buildable stained glass windows to the grand Great Hall, the set is chock full of easter eggs, including the Sword of Gryffindor and even poor Ron’s flying Ford Anglia car — itself a buildable element.
