Lego may be 70 years old but its popularity continues to grow among kids and adults alike. There is a catch, though: those colourful plastic bricks and minifigures do not come cheap, so it's important to buy from the right place, at the right time, at the right price.

The best places to check for discounted Lego as we head towards Christmas 2019 are (in this order) Amazon, John Lewis, Very, Argos, Smyths Toys and Tesco in the UK, and Amazon and Best Buy in the US. is also offering 30% off selected sets, and is great for checking official RRPs when you're sceptical about another site's offer.

But you don't have to trawl through those sites yourself, because our bargain experts have done it for you. In this article we bring you the best Lego deals we've found across the web in the UK.

Right now Frozen 2 Lego is in serious demand. Amazon has some nice offers on these, as does Smyths. Also keep a special eye out for limited-edition sets, which tend to hold their value, especially if you keep them in good condition. And check our roundup of the best Lego sets for more advice.

Best Lego deals

1. Lego Star Wars X-Wing Starfighter

Argos quotes a 'was' price of only £80, but Very, Smyths and (until it stopped selling the item) Amazon agree that the RRP is £89.99 so we're going with that.
