And here’s the best part. You don’t have to go running into a wall and hoping it’s a train platform to get it. It’s actually part of a Prime Day discount over at Amazon. For a limited time, this Lego set is available at a 20% discount. That makes it just $136 down from $170, which is $34 off its normal price.

Dozens upon dozens of LEGO sets are discounted, including options from popular franchises (and even LEGO advent calendars ). Grab Harry Potter’s Hogwarts castle, the Super Mario piranha plant, a Walt Disney tribute camera and countless more unique sets. I’m not even into LEGO’s and I might have to purchase one or two.

This Amazon Prime Big Deal Days, Lego sets are on sale, up to 45 percent off. Fans of ‘Star Wars,’ ‘Harry Potter,’ Disney, and Lego flowers can snap up kits for less. Stock up on Legos this October Prime Day before the sale event ends October 9 at midnight PT.
