We got married when we were older and both of us had our own households set up already. People kept asking us what we wanted, and I kept saying, "Nothing, just come to our wedding and celebrate with us. We don't need anything." We still got money and gift certificates (this was when gift cards weren't that common), so I think the people who ask for money outright are making a big mistake - not only is it rude to assume that people are giving you gifts, it's tacky. I was very touched by an elderly aunt who sent us $20; she was on a fixed income, so, for her, $20 was a lot. I thanked her for it very much, too.
