Is LEGO Renewable Energy Add-On Set a good investment?
Renewable Energy Add-On Set currently trades 39.1% above its $100 retail price, and it is retired, so no new supply is entering the market.

Why is LEGO Renewable Energy Add-On Set so expensive?
Renewable Energy Add-On Set was released in 2010 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.
