Old Navy credit cards can be used wherever Visa is accepted. However we don’t recommend you to apply for store credit card because of its high interest rate and the lack of some bonuses. If you want to earn rewards on all purchases, we recommend you to apply for a general rewards credit card. You can find best credit cards for shopping here. Depending on the rewards card you have, the reward points you earn could possibly be redeemed for award gift certificates, travel or more. A good example of rewards card is Discover cards. Some cards allow to earn up to 5% cash back in rotating categories. In addition, if you shop at Old Navy through Discover Deals, all your purchases will earn a 5% cashback bonus.
