If you've heard of a gift registry but aren't sure what it is, let us first define a gift registry. A gift registry is a service that allows people to make a wishlist of things they'd like to receive for any occasion. While wedding and baby gift registries are the most popular, you may also build a gift registration for your birthday, anniversary, housewarming, or any other occasion. This gift registry is then shared with visitors, who can choose items within their budget from it. With a gift registry, you can avoid receiving items that you would never use, and your visitors won't have to waste time deciding what to get.
