SMYTHS Toys store has launched an offer that means you can get up to £10 off Lego sets in-store and online.
You'll have to spend £50 to qualify for the discount, but there's also a cheaper offer that knocks £5 off a £25 spend.
The £10-off and £5-off only applies to Lego toy sets at Smyths and the discounts will end on Monday.
You don't have to do anything to redeem the offer and it will be automatically applied at the checkout.
Shoppers will need to make sure they have Lego items in their basket that either add up to £25 or £50 in total though, as the discount doesn't apply to non-Lego products.
For example, the deal means you could pick up a Harry Potter Hogwarts Moment set, which would usually cost £26.99, for only £21.99 in the offer.
On Amazon the same set costs nearly £27 too, so the Smyths discount will save you a fiver.
The deal can be applied to sets that have already been reduced too.
For example the Lego City airport passenger airplane and terminal toy was £89.99 at full price and has now been reduced to £79.99.
The extra £10 discount brings the total price down to £69.99.
However, it's worth noting you can buy the same set from Very for £69.99 too which has been reduced from from £90, making it a straight £20 saving instead.
If you're ordering online at Smyths then you usually have to factor in the £2.99-£4.99 charge for delivery.
It's free for spends over £15 and if you're taking advantage of the discounts you will spend at least £20 anyway.
It will take up to four days for your order to arrive though.
If you can't stand the wait, a lot of the sets are available in-store too, where the discount will be applied when you head to the checkout - use Smyths store finder to find your closest.
You can't use the discount on video games though, and another term in store will stop you from redeeming the discount multiple times within one household.
Smyths launched a massive Lego clearance sale last month where the toys were up to 75% off.
Plus Poundtoy has launched a huge spring clearance sale too, where toys like LOL Surprise!, Disney and Paw Patrol start at just 1p.
But one mum wasn't a fan of the building block toys when she was left horrified after catching her toddler trying to buy £28k of Lego online.
