I never got an invitation that wanted gift cards only. It does seem tacky, but maybe there's a reason.I personally would never put that on an invite. My daughter just got married in April. And there were 2 showers. One was up north where we used to live given by her Maid of Honor and a Bridesmaid and I had one for her work friends. The guests knew where she was registered and some got gifts from the registry and others gave gift cards or money.I just drove the gifts from the up north shower back home with me.She got the things they really wanted with the gift cards.Some of the ladies got her frilly baby dolls and sexy underwear.
