Where can I get the combo ticket for d’orsay museum and l’orangerie museums?

There is no longer a combo ticket, unfortunately.

The thing Thread wear linked to is a year-long membership card, which is probably a bit expensive for a one-time visitor.

I have one, but I live here, so the economics of the card make more sense for me.

I think the D'Orsay now combos with another museum?
