This NASA web site claims almost half a billion dollars per mission.

IIRC, the cost of shuttle missions ended up being about way higher
than initial estimates (ten times?), partly blamed on there being far
fewer launches than was assumed when the estimates were made.
Here's an interesting graph of plan vs. actual budget:
