How LEGO Price Comparison Works
Brick Sleuth tracks LEGO set prices across all major UK retailers every day. We compare prices from Amazon, Argos, John Lewis, Smyths Toys, and the official LEGO Store so you don't have to visit each site individually.
Every set on our site shows the current cheapest price, the recommended retail price, and the discount percentage. You can see at a glance which retailer offers the best deal for any LEGO set.
How to Find the Best Price
- Search or browse – Find a set by name, number, or theme using our full catalogue.
- Compare prices – Each set page shows current prices from every retailer that stocks it.
- Check the price history – Our price graphs show how the price has changed over time so you can decide if now is a good time to buy.
- Set up alerts – Add a set to your watchlist and we'll email you when the price drops.
We also highlight sets at their best ever price and the biggest current discounts to help you save even more.
