For as long as you'd like! You have full control of when your gifts ship and the ability to exchange gifts before they ship in your gift tracker.
However, if you wait too long, we cannot guarantee the availability of the item. This rarely happens, but if the gift is out of stock or is discontinued by the manufacturer, you can convert the gift into Zola store credit and use it on any of the 50,000 gifts in our store. You can learn more about Zola store credit here.
