You don't necessarily have to purchase that wedding gift all by your lonesome. A whole new selection of gifts are now attainable. If no one in your group is well acquainted with the bride or groom, talk to someone who is. Find out their tastes, likes, and dislikes. When spending Big Bucks, it's wise to give a gift they'll enjoy, and not something they already have.
Most couples enjoy receiving a large screen TV, or a great sounding stereo system.
Furniture is a popular choice, as long as you're aware of the couples tastes. I understand people have even bought cars and houses for the wedding pair. I've only heard or read this, not actually witnessed it. All I can say is the couple must have been some deserving. At many Travel Agencies couples can register their honeymoon and have family and friends help pay for it.
