Price to charge to add Chosson and Kallah pic into fam pic

What is the norm to charge to add a chosson and kallah pic into a family pic?
I was thinking $75 - is that too much, too little?

I was wondering about such pricing too, so if you get any smarter, please post the price!

photographer charged my fam that much to add the chosson and kallah. I think thats normal price.

i charged 100 and they were okay with that too…
