These are the best Lego Black Friday deals you can get this year, including steep discounts on Super Mario and Star Wars sets.

Here are eight Lego Cyber Monday deals to check out. And don’t wait, as once Monday’s over, the deals go poof and disappear. (Oh and be warned: If a set says its on “back order’’ you might not get it in time for Christmas.)

Walmart currently has Black Friday deals going on dozens of sets from Harry Potter, Super Mario, Star Wars, Marvel and more, dropping the price by a whopping 30% in many cases.
