Keep an eye on our social media presence and be sure you're getting our newsletters - we do provide promotional discount offers from time to time. We do also offer a PayPal credit plan for students who need assistance paying for their Nanodegree program in installments. You can find this option on our checkout page, and set up PayPal credit with PayPal beforehand to learn more about how it works.
