Wedding gift question

[OtterXO]

So none of the previous wedding gift threads discussed this and my internet search concluded with the options of giving cash or a gift card so I figured I'd ask you all. I'm in the bridal party for a destination wedding (the second marriage for the bride, first for the groom). The couple already lives together and have two kids. They haven't registered anywhere and since they've been living together for some time, I can't imagine they need random household stuff (i.e. platters, serving bowls, etc.). Any suggestions for a gift besides cash or a gift card? I'm planning on spending about $100.
