Brick Broker, how a brick price comparison site works
At Kadris, we create the wall art that showcases your sets once they're built. But it all starts earlier: with buying the set, at the right price. That's why we partnered with Brick Broker, the French reference for brick price comparison. This first article opens a series where, month after month, we explain what they do and how to make the most of it.
What exactly is a price comparison site?
The principle is simple. The same LEGO® set is almost never sold at the same price everywhere. Between big retailers, specialist shops, marketplaces and current promotions, the gap can reach 30, 40, sometimes 50%. A price comparison site continuously scans all these retailers and shows, for each set, who sells it cheapest at the moment you look.
In practice, you type in a set's name or number, and you see the best available price, without having to open fifteen tabs yourself.
What Brick Broker lists
Brick Broker tracks over 34,000 sets. The site's strength is that it doesn't stop at LEGO®: it also covers alternative brands like CaDA, COBI, Mould King, BlueBrixx, Sembo, Sluban and others. A great way to compare, and sometimes discover models you'd never spot in a shop.
Why it matters for an enthusiast
An Icons or Technic set is a real investment. Buying at the right time can save you enough to treat yourself to the matching wall art. And above all, a comparison site spares you the regret of discovering, two days after buying, that the same set was 40 euros cheaper elsewhere.
The ideal journey, in our view: spot the deal on Brick Broker, build at your leisure, then hang it on the wall with a Kadris frame.

Use the comparison tool wisely
Start with the exact set number to avoid mixing up editions. Compare the displayed price, availability and retailer, then open the retailer's page to confirm the final total. Shipping costs, delivery times and return conditions can change which offer is genuinely best.
- Confirm that the item is in stock.
- Check the final price before paying.
- Use nearby models as alternatives if the budget is exceeded.
Brick Broker is an independent comparison tool. Its data is collected automatically and remains indicative, so the retailer's page is always the final reference.

Brick Broker, how a brick price comparison site works: how to use price information well
Quick answer: a comparison tool is most useful when it helps verify the real delivered price, seller conditions and recent price movement—not simply the largest percentage shown on screen. Start with the exact set reference, compare like with like and check whether delivery, membership or marketplace fees change the final cost.
What should be compared besides the headline price?
Check stock status, seller identity, shipping costs, delivery time and whether the offer is for a new, complete set. A low figure can be less attractive once postage or conditions are added. For a gift, delivery reliability may matter more than saving a very small amount.
How do price alerts help?
An alert can reduce impulse buying by giving you a target and notifying you when an offer approaches it. The target should reflect your budget and purchase deadline. It is still worth reviewing the current offer manually because prices, stock and seller terms can change quickly.
Do retired sets need a different approach?
Yes. Availability becomes less consistent after retirement, and marketplace listings can vary greatly. Confirm the exact reference, box condition and seller protections before paying a collector price. Historical trends are useful context, but they do not guarantee that a set will rise in value.
How does this connect with displaying a collection?
Plan the final location before buying a large model. A good price does not solve a lack of space. Measuring shelves or wall areas in advance helps prioritise the sets that genuinely fit your collection and avoids leaving an expensive build in its box.
Prices and availability can change. Always verify the retailer's live terms before ordering.
