Best September deals on Lego Icons and Adult sets
Our pick: Botanicals Chrysanthemum
*Average price in the last six months: £24. Cheapest price in past six months: £12
Number of bricks: 278
Watch out for: Speedy build time
This Lego Botanicals Chrysanthemum captures the flowers in bud, blooming and full bloom with leaves and petals which can be posed to achieve the desired look.
It even comes with a wood-effect plinth to display it once you’ve finished building. Do keep in mind that if you're looking for a long, complicated build this may not be for you.
Runner-up: Project Hail Mary
*Average price in the last six months: £143. Cheapest price in past six months: £87
Number of bricks: 830
Watch out for: Takes up quite a bit of space
This microscale spaceship model kit features the iconic interstellar spacecraft, functional display stand, Ryland Grace minifigure and Rocky figure.
You can even send the crew module into orbit by turning the crank, simulating the centrifugal gravity system from the film. Be aware that once built the model will stand over 12 inches (30cm) high, 9.5 inches (25 cm) long and 8.5 inches (22cm) wide, so make sure you have somewhere suitable to display it.

Top deals on Star Wars Lego
Our pick: Offworld Sandcrawler and Mudhorn 75453
*Average price in the last six months: £176. Cheapest price in past six months: £150
Number of bricks: 1,683
Watch out for: Not as many minifigures as some similarly priced sets
While this set may be slightly scaled down compared to older sandcrawler sets, this moving scrap market still has plenty of play features. It includes a fully furnished interior, a handful of Jawas from season one of The Mandalorian, plus figures of Grogu, Kuiil, and The Mandalorian himself.
The price tag hasn't taken a huge hit, but it is the first discount we've seen on a newer set from this theme.

Best September deals on Harry Potter Lego
Our pick: Hogwarts Castle: The Main Tower 76454
*Average price in the last six months: £205. Cheapest price in past six months: £138
Number of bricks: 2,135

Just know that this is a 'dollhouse' version of the castle, meaning it's not fully enclosed.

When is Lego discounted?
It's likely that throughout the year many retailers will have their own deals going on. Plus, Lego itself may have some deals themselves — especially on sets that are going to be discontinued soon. You can check Lego's deal page, and check which sets are being retired soon from their website.
How can I save money on Lego sets?
While we can't put a firm number on how much a set is typically discounted, there are usually several on sale throughout the year, so we'll keep an eye out and update this page with the best deals we find.
You'll typically find most deals from third-party retailers instead of Lego themselves. While you'll usually get some extra goodies thrown in when you buy direct, it may not be worth the the extra savings.
Where can I buy discounted Lego sets?
At the moment, most Lego deals can be found on Amazon, Argos, Smyth's Toys and Very. They'll often sell Lego sets cheaper than on Lego's own website.
You can check the stock of what each retailer has on sale below and see their full offerings:
If you're looking for more sets, you can take a peek at Lego's sales and deals page.
As a general rule of thumb, paying 10p per brick/part is a pretty typical price for Lego. Branded and franchised Lego sets like Star Wars, Disney, Mario, Marvel, and Harry Potter tend to be a bit more expensive – at around 11 to 12p per brick.
Lego's own-branded set lines that don't use as many set-specific parts like Icons, Ideas, Classic, Modular buildings, and Creator – will tend to cost around 7 to 8p per brick.
Should I buy direct from Lego?
You can find some discounts direct from Lego, but it's still one of the more expensive options. You can see which sets have been discounted on Lego's website.
Lego isn't cheap – to make or to buy. While you can generally get sets cheaper by buying from other retailers, there are still perks to picking up your pieces from Lego itself.
Sometimes when you order directly from the Lego store (either online or in person), you'll get a small bonus set when you spend past a certain threshold or buy a certain set. The bonus gift tends to change each month, and sometimes you can even get multiple gifts. Keep track of the bonus free sets on Lego's website.
You can also sign up to Lego's Insider programme where you earn points to get money off future sets and access to exclusive sets and deals.
