LEGOs are one of the most popular toys out there because they are not only fun, they also spark creativity in kids, tune their fine motor skills and boost their emotional development. Any toy that provides our kids with an outlet to build and be creative is a winner in our book — although, we have to say we hate stepping on the darn things! Nevertheless, we can take the LEGO pain if it means our kids are learning and playing (and busy) at the same time.

So when we see LEGO sets on sale, we can’t help but jump at the opportunity to buy them up. Right now, Amazon has marked down tons of LEGO sets by 20 percent off, including the ever popular LEGO Duplo Frozen set.

Younger kids can become brick-building masters with this set that features 17 larger LEGO pieces suitable for kids from 2 and up. With “Frozen” favorites such as Elsa and Olaf, kids can let their imaginations run wild as they act out a fun tea party with the included icehouse, teapot, hot chocolate and cakes. 

For kids 7 and up, check out the LEGO Marvel Avengers Iron Man Hall of Armor playset — which has a nearly perfect 4.9 rating on Amazon — which is  quite ambitious, with524 pieces. It includes five minifigures, a rotating podium with detachable modules that can be combined and stacked in many different ways, and an Igor Suit featuring a minifigure cockpit. This is what superhero dreams are made of, and this exciting set is also on sale right now. Shop the below deals now before prices go back up!
