I Already Bought a Gift Via the Wedding Gift Registry. Should I Still Bring Them a Card at the Wedding?

I wouldn't put money in the card since I already spent quite a bit. But just a Congratulations card. I feel uncomfortable going empty handed, but what is the general standard?

Suggestion:

It is not required to bring a card to the wedding if the gift is already delivered. These days, the card box is for those that are giving money in a card, the expectation is that there will be money in the card when it is opened, and there will be a failure to understand why if there is not money in it. . A congratulations card is not expected. But if you wish to, fine. Miss Manners says we are supposed to walk in empty handed, that the gift is supposed to be delivered to the bride or a designated place before the wedding. As you did.

In these days of bride's having a card box, and a wishing well, and a dollar dance, and the groom having a dollar dance, in addition to the expectation of expensive wedding gifts, coming with a card is redundant. Likely you will be expected to participate in an additional money gathering scheme at the wedding. I am am not criticizing the bride's dollar dance, in some cultures it is not done just for the money, but for luck. I am criticizing those that do not belong to those cultures, who do it for the money. And leaving uncomfortable guests digging for money in pockets, thinking, hmm, they are not Italian, I did not expect this.
