I guess it depends if we get the "Making Ghostbusters" book as it's pretty rare. The book, 2 extra discs of bonus features and the special edition packaging for $33 Cad more than the SRP of one movie and two discounted retail prices seems reasonable though. The same listing is $149.99 USD on Amazon US.
Damn the Amazon version is $60 more: https://www.amazon.com/Ghostbusters-II-Afterlife-Gift-Blu-ray/dp/B09LGK58M5
