Old Navy typically allows customers to use multiple gift cards for a single purchase, making it convenient for those who may have several cards they would like to combine. When making an online purchase, customers can enter the details of each gift card during the checkout process. This feature also generally applies to in-store purchases, where cashiers can process multiple gift cards for one transaction. However, it is always important for customers to be aware of any specific limitations or changes that may apply to gift card usage, so checking the official Old Navy website for the most current information is a good practice. Each store policy may vary slightly, so it is beneficial to familiarize oneself with the details provided by Old Navy directly.
