Is LEGO Ultra Agents Ocean HQ a good investment?
Ultra Agents Ocean HQ currently trades 220.4% above its $138 retail price, and it is retired, so no new supply is entering the market.

Why is LEGO Ultra Agents Ocean HQ so expensive?
Ultra Agents Ocean HQ was released in 2015 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
