1. LEGO Icons 10297 Boutique Hotel
- Reported Prime Day Discount: You got it at $159 (30.4% off RRP $229.99). This is the best deal on this list.
- Pieces: 3,066
- Retirement Date: December 31, 2025
- Why it’s a Top Pick:
- Modular Building: This is the #1 reason. Modulars consistently and reliably appreciate significantly after retirement. They are a cornerstone of many AFOL collections, and collectors must have them to complete their street.
- Imminent Retirement: Retiring at the end of 2025 means a rapid increase in aftermarket value once it’s gone from retail.
- Exceptional Entry Price: Your 30%+ discount is fantastic for a Modular, immediately building in a substantial profit margin.
- Popular Design: The Boutique Hotel is well-regarded with unique angles and details, ensuring sustained demand.

2. LEGO Marvel 76178 Daily Bugle
- Reported Prime Day Discount: 20% off (RRP $349.99, so around $280)
- Pieces: 3,772
- Retirement Date: Initially December 31, 2025, though some reports indicate a potential extension to late 2026. However, the prevailing sentiment is still a 2025 retirement, making it an urgent buy.
- Why it’s a Top Pick:
- Minifigure Goldmine: This set is packed with an unprecedented number of highly desirable and exclusive Marvel minifigures (Spider-Man, Venom, Green Goblin, J. Jonah Jameson, Daredevil, Blade, Punisher, etc.). Many of these figures are exclusive to this set and unlikely to be re-released soon. Minifigure collectors will pay a premium.
- Iconic Location: The Daily Bugle is an instantly recognizable and iconic Marvel landmark, making it a fantastic display piece.
- Large Scale: A massive set with a high piece count for adult collectors.
- Good Discount: 20% off a set of this size is a solid deal.

- Pieces: 2,065
- Retirement Date: December 31, 2025
- Why it’s a Top Pick:

4. LEGO Star Wars R2-D2 Droid Building Set (75308)
- Reported Prime Day Discount: 20% off (RRP $239.99, so around $192). Note: Some sources say this retired Jan 2025, but if it’s still available on Amazon for Prime Day, it’s either old stock or an updated retirement. If it’s truly retired, the discount is a steal, but if it’s still current, the 20% is good.
- Pieces: 2,314
- Retirement Date: Reportedly January 2025, but if it’s available for Prime Day, treat it as very, very imminent retirement, or perhaps an extended run until end of 2025.
- Why it’s a Top Pick:
- Iconic Character: R2-D2 is universally beloved and a central figure in the Star Wars saga. Builds of iconic droids are highly sought after.
- Display Piece: This is a fantastic display model for any Star Wars fan.
- Collector’s Item: As a large-scale, detailed buildable character, it appeals to a strong collector base.
- Star Wars Brand Power: Star Wars sets consistently do well in the aftermarket.
- Investment Rating: 8/10 (Strong due to iconic character and display value, but check if it’s actually still active for retirement window)
5. LEGO Technic Lamborghini Sián FKP 37 (42115)
- Reported Prime Day Discount: 30% off (RRP $449.99, so around $315)
- Pieces: 3,696

- Imminent Retirement: Retiring at the end of 2025 means it will soon become a “grail” item for those who missed it.
- Strong Discount: 30% off a set of this price point is a very good entry.
- Investment Rating: 8/10 (Excellent for Technic collectors, but a higher initial capital outlay)
Important Reminders for Prime Day Buying for Investment:
- Verify Retirement Dates: While I’ve given the most current information, LEGO retirement dates can sometimes shift. A quick search on BrickEconomy or similar sites is always recommended.
- Check Stock Levels: Prime Day deals can sell out extremely fast, especially for highly desirable sets.
- Condition of Box: For investment, maintaining the box in pristine, factory-sealed condition is crucial for maximizing aftermarket value.
- Shipping Costs/Fees: Always factor in potential shipping costs (if not Prime eligible) and any selling fees (eBay, BrickLink) when calculating your potential profit.
