When you order on PrintzGalaxy.com there are 2 payment methods via PayPal and Credit Card (Visa, MasterCard & American Express). Why did my credit card payment fail? Payment by credit card may fail due to bank authorization and fraud prevention systems. If you are having trouble making a payment via Credit Card, you can contact the card issuing bank or PayPal directly. Important information is that we do not accept payments separately in one invoice.
