How often do LEGO sets actually go on sale? What five months of price data show
We tracked 911 LEGO sets across 19 Danish retailers from late April to late September 2026. The short answer: almost always. The longer answer is which themes, how deep, and how fast after launch.

"Wait for a sale" is the most common piece of LEGO buying advice, and also the vaguest. How long is the wait? How deep does the sale go? Does it depend on the theme? Since Brickheist records every price change at every retailer we track, we can answer those questions with data rather than folklore. This article uses our Danish price history, which is our deepest dataset: 911 sets with an official recommended retail price, 19 retailers, every price change logged since 28 April 2026.
How we measured it
For each set and each day, we took the lowest in-stock price across all retailers and compared it to LEGO's recommended retail price (RRP). A day counts as "on sale" if that lowest price is at least 3 % below RRP, which filters out rounding and currency noise. We only included sets with at least ten days of observations. Because we log changes rather than daily snapshots, the day counts are approximate, but the picture they paint is not subtle.
The headline numbers
- 95 % of sets were below RRP somewhere on most of the days we observed them.
- On average, a set's cheapest price sat below RRP on 83 % of days.
- Only 1 % of sets were never discounted at all in the period.
- The median set's deepest discount was 42 % off RRP. Half of all sets could, at some point, be bought at less than 60 % of the official price.
In other words, in a market with many competing online retailers, the recommended retail price is not the normal price. It is the ceiling. The interesting question is not whether a set will be discounted, but by how much and where.
Which themes are discounted most
The share of days below RRP is high everywhere, but the depth of the discount varies a lot. Sorted by how often the cheapest price was below RRP:
| Theme | Sets | Days below RRP | Median deepest discount |
|---|---|---|---|
| LEGO Editions | 20 | 90 % | 42 % |
| Botanicals | 31 | 88 % | 47 % |
| Speed Champions | 30 | 88 % | 42 % |
| Friends | 48 | 87 % | 45 % |
| Super Mario | 20 | 86 % | 43 % |
| DUPLO | 46 | 86 % | 46 % |
| Technic | 60 | 86 % | 42 % |
| NINJAGO | 45 | 86 % | 41 % |
| Disney | 49 | 85 % | 42 % |
| Minecraft | 31 | 85 % | 44 % |
| Star Wars | 74 | 85 % | 43 % |
| City | 71 | 84 % | 42 % |
| Creator 3-in-1 | 45 | 83 % | 43 % |
| Harry Potter | 40 | 81 % | 40 % |
| Icons | 48 | 79 % | 32 % |
| Marvel | 50 | 78 % | 39 % |
| Jurassic World | 15 | 72 % | 36 % |
| Ideas | 24 | 71 % | 29 % |
Two things stand out. First, the mass-market play themes and the display lines that sell through supermarkets and department stores (Botanicals, Speed Champions, Friends, DUPLO) are both discounted most often and most deeply. Second, the adult-oriented lines that rely on LEGO's own shops and specialist retailers, Icons and Ideas, are still below RRP most of the time, but the deepest discounts are far shallower: a median of 29-32 % against 42-47 % elsewhere. If you are waiting for a Botanicals bouquet to hit half price, history says it probably will. If you are waiting for an Ideas set to do the same, history says you may be waiting a long time.
How fast after launch?
We looked at the 89 sets released between May and mid-August 2026 that carry an RRP in our Danish data. Of those:
- 25 were below RRP on or before release day, usually through pre-order pricing at online retailers.
- 39 more went below RRP within two weeks of release.
- Only 9 took longer than two weeks, and 16 had not been discounted at all by late September.
That means roughly seven in ten new sets were cheaper than RRP within a fortnight. The early discounts are shallow, typically in the 5-15 % range, because they come from retailers who price everything slightly below RRP as policy. The deep cuts of 30-50 % come later, when a set has been on shelves long enough for stock to build up, or when it is being cleared before retirement.
What this means when you buy
- Never treat RRP as the price. Compare first; the odds that the set is cheaper somewhere are better than nine in ten.
- Decide which kind of discount you are waiting for. A 10 % saving is available almost immediately. A 40 % saving exists for most sets, but it is a moment, not a state: it appears at one retailer, sometimes for days, and then disappears. A price alert on the set page catches it without you checking every day.
- Calibrate by theme. For Icons and Ideas, a 20-25 % discount is a genuinely good price. For City, Friends or Botanicals, it is Tuesday.
- Check the price history before you celebrate. The chart on every set page shows whether today's "offer" is the lowest we have seen or just the usual level. Our guide on reading a price chart walks through it.
Caveats
This is Danish data from a five-month window that does not yet include Black Friday or the January sales, so the discount depths here are, if anything, conservative. Retailer coverage differs by country: our UK data covers fewer shops, and the share of days below RRP there is lower. We will update these figures in the monthly price report as the dataset grows.
