I think a 100 dollar gift card somewhere they like and maybe something little to actually open is appropriate. Like a Sephora gift card and some of their favorite candy.

Are they married, engaged, or otherwise long term partners? Or is this just a newer girlfriend/boyfriend etc?

If long term partners just make the check or gift card out to both together. Maybe with some small item to open.

If a new boyfriend or girlfriend, GC for $50-$100 and maybe a small item to open is more than enough. They won’t be expecting much.

ILs gave $500 checks to all at Christmas, my parents gave $150 GCs to place of our chosing. Always equal amounts to their child and DIL/SIL

Working means both are employed with lits of earning years ahead, not students or jobless, while parents are at the end of their earning years.

Every family has different family traditions/norms around gift giving. So do whatever feels right for your family.

But I’d say $50 would be good.

$100 is perfect.

Just make the check out to the couple, no need to give a separate spouse gift.

$100 sounds nice. I personally wouldn’t mind if I got $100 and dh got like $400 worth of gifts. If I got some crummy candle and he got $$$ gifts I’d be a little put off.

My parents just give one check and address it to both of us. We have joint checking after all, so it’s going to the same place.

Don’t be too disproportionate between what you give the spouse and what you give your child. $100 each? Plus some actual objects ss gifts.

I cannot follow the question. Is this old parents giving daughter in law a gift or the reverse and what does working matter.

$50 and a small gift is fine. $100 and a small gift is nice. For small gift could be something you know they’ll like, consumable etc.

How ever much you want. $100-100,000

I read this as "help! I cannot relate to the poors!"

They are in their early 30's and parents are near retirement mid 60's.

How much would you give?
