Accept Discover Credit Card as payment method.
I am in utter disbelief to learn that I cannot pay my bill because my business uses Discover. Discover is one of the most popular networks, what gives? Why???

My business uses Discover as well. Right now to use my Discover Card I have to add funds via PayPal to cover my invoices every month. It would be nice to add my Discover Card as default form of payment and getting charged automatically.
