Currently, $20.72 right now on Amazon from a third party, but fulfilled by Amazon. This is the cheapest I have seen the game.
The Days of Thunder Game and Movie hybrid has been standing still at $29.99 for a long time. Both Top Gun and Days of Thunder are available as standalone downloads on PSN. The movie and the game are on the same Blu-Ray disc and I never heard any confirmation if the movie will work on a standalone blu-ray player or not.
EDIT: Will work on standalone Blu-Ray players.
