If Lego is not your thing, Prime Big Deal Days has lots of other stuff on sale as well. You can save big on laptops and iPads, get the James Bond movie collection for 50% off, or grab the newest edition of Harry Potter Monopoly for a magically low price.

Sometimes you want to go to space with your LEGO Friends. The Mars Space Base and Rocket set ($55.99, 30% off the list price of $79.99) comes with a spaceship toy, rover, and Mars research base with different pods, and it comes with three mini-dolls and a cat figure to colonize the Red Planet.

Looking for viral LEGO sets on sale during October Prime Day? I found not one but five options (including the mega-popular Super Mario LEGO set) for a steal. But you'll have to hurry to secure them on sale because the sale ends in less than 48 hours.
