LEGO price report: September 2026
The first of our monthly reports: how many sets are below RRP, how deep the discounts run, how quickly new sets are cut, what happens to retired sets, and what to watch for in October.

This is the first edition of a monthly report on the LEGO market as Brickheist sees it. Each month we will publish the same handful of measurements from our own price history, so that changes over time become visible. All figures below are from our Danish dataset, which is our most complete: 19 retailers, every price change logged since 28 April 2026, measured on 23 September 2026.
The market in numbers
- 976 active sets with 100 pieces or more and an official RRP.
- Median discount on the cheapest live price: 34 % below RRP.
- Median price per piece: 0.86 kr at RRP, 0.62 kr at the cheapest live price.
- Retailer spread: for sets stocked by three or more shops, the most expensive is a median 58 % dearer than the cheapest.
How often sets are discounted
Across 911 sets with at least ten days of history, the cheapest price was below RRP on 83 % of observed days, and 95 % of sets were below RRP on most days. Only 1 % of sets were never discounted. The median set's deepest discount was 42 %. The most heavily discounted lines were LEGO Editions, Botanicals, Speed Champions and Friends; the least were Ideas, Jurassic World, Marvel and Icons.

New releases
Of 89 sets released between May and mid-August, 25 were already below RRP on or before their release day and a further 39 within two weeks. Sixteen had still not been discounted by the end of September, and they are mostly large adult sets and exclusives. Early discounts remain shallow; the deep cuts on this summer's wave are still to come.
Retired sets
Fifty sets in our catalogue are marked as retired with price history on both sides of the retirement date. In the six weeks before retirement, their cheapest price sat at a median 80 % of RRP. After retirement it rose to a median 87 % of RRP, as the cheapest listings sold out first and the remaining stock was priced closer to full price. That is the pattern described in our guide to retiring sets: the last weeks before retirement are usually the cheapest a set will be as new, sealed stock.
What to watch in October
- Pre-Black Friday positioning. Historically the deepest cuts of the year arrive in late November. Prices in October often tighten first, as retailers avoid discounting stock they plan to promote. This dataset has not yet seen a Black Friday, so November's report will be the first with those figures.
- Retiring stock. Sets on LEGO's own retiring-soon lists tend to be cleared by third-party retailers in the autumn. Our retiring soon page lists the longest-running sets still in stock.
- The autumn wave. Sets released in August and September are entering the window where the first real discounts appear.
Method
Prices are fetched daily from every retailer we track and every change is logged. "Below RRP" means at least 3 % under LEGO's recommended retail price, to exclude rounding noise. Medians are used throughout because LEGO prices are heavily skewed by a small number of very large sets. How the data is collected is described on our methodology page; no retailer pays for placement.
