Is $1200 too much for my husband to give his sister as a wedding gift? Am I wrong to say it’s too much and comment about it to him?

Sister in law is on her second marriage and she’s only 25. Besides the point we have her 1000 on her first wedding, already feel
like we do a lot for her. She got divorced and getting remarried. Husband rented a car from turo for them which was 700$ and wants to give an additional 500$ cash. We share bank accounts and both work. We moved into a new house and she never even got us a house warming gift. Am I wrong to say it’s roo
much or should I just not get involved?
