Is LEGO BASH! retired?

What is the price per piece for BASH!?

Is LEGO BASH! a good investment?
BASH! currently trades 49.6% above its $20 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO BASH! so expensive?
BASH! was released in 2017 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.
