Check out this Lego Classic Medium Creative Brick Box playset. It's usually sold for $34.99, but it's on sale on Amazon for just $24.99.
If you prefer to shop in-store, I found it at Walmart for $20.99 as well.
Use Amazon's 'Toys We Love' list as a guide to see what toys are popular this year and bookmark KCL's Toy Deals page so you won't miss out on savings.
