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 1,337 LEGO sets in Polish stores over 30 days with data. The median set price was 148 zł, and the average 254 zł. The median price per piece is 0.33 zł. Sets were typically 30% cheaper than the catalog price (median across a sample of 1,337 sets with a listed catalog price), and 926 sets were on promotion (at least 15% below catalog). Month over month, the median price fell by 0.6% (across the same 1314 sets).
Day-to-day prices for individual sets are collected by our LEGO price comparison.
Is LEGO getting cheaper?
LEGO got cheaper: the median price of a tracked set fell by 0.6% month over month, across the same 1314 sets present 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.
Biggest price drops in September 2026
Sets whose lowest offer fell the most over the month (from the highest to the lowest daily minimum price). We show only sets with at least 10 days of data.

Duplo bricks are roughly eight times the volume of a System brick, so these sets simply have fewer pieces for the same money. The zł / piece value is computed the same way as for other themes, but it is not comparable to them, which is why the "System scale" mode keeps it out of that sort.
Retired sets
In September 2026 we recorded data for 5,972 retired LEGO sets, with an average price of 438 zł. Retired sets often rise in value on the secondary market. See retired LEGO sets.
About the index
The LEGO price index is Poland's first monthly report computed from KlockoRadar's own price history. Prices come from dozens of Polish stores, and the data point for each set is its lowest daily offer. We publish the index as open data: you may quote the figures with attribution to KlockoRadar.
