The lesson

LEGO Technic NASA Artemis SLS Rocket (42221) is $49.98 at Amazon. Space fans, this one's for you. It's a 632-piece Technic model of NASA's Artemis rocket with working stage separation, and it's selling well under its list price. It's a strong price on a big display build, just shy of the very bottom. We wouldn't hold out for a couple of extra dollars off.
