If it says no gifts, i will still give a gift. BUT if it requested money to be donated to charity instead then i would definitely do that. But i wouldn't do nothing.

On the other end of that. We requested to wedding gifts at our wedding. Many people bought one, some didn't, and i wasn't fussed at all. I said to gifts and i meant it so was absolutely fine with people no bringing a gift.

So i think both responses are totally acceptable.
