A bridal registry
or wedding registry
, is a service provided by a website or retail store that assists engaged
couples in the communication of gift preferences to wedding
guests. Selecting items from store stock, the couple lists desired items and files this list with the chosen merchant. The list is then made available to wedding guests, either by the couple's family or by the merchant. Upon the purchase of a listed item, the merchant updates the gift registry
accordingly. In addition to providing valuable information for the buyer, the system helps prevent the receipt of duplicate or unwanted gifts, potentially saving time for both giver and recipient.
