Friend relative died. Online card or gift suggestions

[movingoceans]

Hello,

Sadly my friend's grandmother has died, I would like to send her a card, though I do not know where to look. I could post a card to her but our postal delivery has serious backlog and by then, it would be crumbled and she may not receive it in weeks time !

Any suggestions of e-cards online?

Thank you :)

Moon pig have been very quick with my cards, normally next day.
Funky pigeon is another
