Why This LEGO Insiders Sale Is a Must for Collectors and Investors
It’s officially Back to Hogwarts week at LEGO — one of the most anticipated events in the Harry Potter fan calendar. Each September, LEGO marks the return to school at Hogwarts with a wave of magical promotions, including double Insider points, exclusive gifts-with-purchase, and special set launches. This year is no different, but LEGO have gone a step further with an Insiders-exclusive sale on some of the biggest LEGO Harry Potter sets — and many of them are retiring in 2025. That means two things: big savings now and serious long-term potential once these sets vanish from shelves for good.
Biggest Discounts: Diagon Alley, Hogwarts Icons & More
On top of great GWP that we have already discussed in our Back to Hogwarts 2025: LEGO® Harry Potter™ Deals, GWPs & Insider Rewards Guide article, LEGO Insiders will also enjoy:
- 2x Insider Points on selected Harry Potter sets from 1st–7th September.
- Exclusive member savings on additional sets.
For savvy investors, this is a golden opportunity to secure high-value Harry Potter sets while stacking up rewards and bonuses.
Here are our top picks of sets we would buy during this promotion:
