FH's cousin and his now wife(!) eloped about 6 weeks ago. Everyone's known since about a week after it happened, but we just got an announcement in the mail last night and it got me thinking should we send a gift? I think it would be nice to send one, but obviously they're not registered and his cousin is about 16 years older than us so sending a check feels weird. I was thinking maybe a gc to Williams-Sonoma and a card congratulating them, but FH doesn't think we need to send anything. We likely won't see them until Thanksgiving or I'd probably do a nice bottle of champagne and card.
So would you send a gift to a couple who eloped? What would you send?
Bonus question: does the age of the person or couple in relation to your age impact what kind of gift you give (actual present, gift card, cash, etc.)? For any occasion not just weddings.
