Amazon has discounted the impressive 21010 Robie House by 40%. You can pick up the Frank Lloyd Wright architectural standard for $119.93, down from $199.99 MSRP. This is the lowest price we’ve seen on this set and will probably be the lowest ever. Free shipping and no tax to most states makes it an even sweeter deal. Better act fast before Amazon realizes that Walmart sold out and they no longer need to price match.

But wait, there’s more! Amazon has also discounted 21009 Farnsworth House in a similar fashion. That set is discounted 39%, $36.42 down from $59.99 MSRP.

Other LEGO Architecture sets are seeing modest discounts as well.
