If you're looking for LEGO discount codes, it's well worth it. LEGO is a long-standing favourite for parents; the kids love it and it can be a great way of getting them off-screen and learning. The multi-coloured bricks are a great example of a STEM toy – helping kids learn about science, technology, engineering and maths – and they regularly feature in round ups of the best toys. In fact, when LEGO was invented, its Danish founder, Ole Kirk Christiansen, created the name LEGO by taking the first letters from the phrase ‘Leg Godt’ which means ‘play well’ in his native language.

LEGO is so popular that National Geographic claims that there are currently a whopping 80 bricks for every person on earth and last year alone, 340 million Minifigures were produced. During the Christmas period, 28 sets are sold every second and total 220 million around the world, each year.

But the catch for parents is that LEGO is pretty expensive – especially if you’re after a set linked to a franchise like Star Wars, Batman or Harry Potter (although we did find some great cheap LEGO sets). A Hogwarts Castle and Grounds set, for example currently sells for £149.99 direct from Even a small Batmobile will set you back £24.99.

There are, however, ways to get new LEGO sets for less, if you know where to look.
