LEGO price index: September 2026
Poland's first monthly LEGO set price index, computed from our own price history across dozens of Polish stores. Updated daily.
In September 2026 we tracked the prices of 1,317 LEGO sets in Polish stores over 1 day with data. The median set price was 148 zł, and the average 250 zł. The median price per piece is 0.33 zł. Sets were typically 29% cheaper than the catalog price (median across a sample of 1,317 sets with a listed catalog price), and 949 sets were on promotion (at least 15% below catalog). Month over month, the median price fell by 0.4% (across the same 1311 sets).
Is LEGO getting cheaper?
The median price of a LEGO set was practically unchanged month over month (-0.4%), across the same 1311 sets tracked in both months.
Methodology: for each set we take the average of its lowest daily offer in the given month, and we compute the month-over-month change only on sets present in both months, so a change in the catalog composition does not masquerade as a price move.

Klocki Duplo mają objętość około ośmiu klocków System, więc te zestawy mają po prostu mniej elementów za te same pieniądze. Wartość zł / element jest policzona tak samo jak dla innych serii, ale nie jest z nimi porównywalna, dlatego w trybie "Skala System" nie sortujemy jej razem z resztą.
Retired sets
In September 2026 we recorded data for 5,736 retired LEGO sets, with an average price of 432 zł. Retired sets often rise in value on the secondary market. See retired LEGO sets.
