A refund can only be made to the card used to pay for the order. An item that you received as a gift cannot be refunded, but it can be refunded to the person who made the purchase.
On the other hand, if the product has not been opened, it can be replaced without its receipt. To exchange a product, it is sufficient to go to a Diptyque store. This is an opportunity for those who want to replace their gift to walk around, dream and discover, who knows, a hidden treasure.
