We have a redshop site which confirms the credit card and allows us to charge part and shipping once we determine the full amount. This is not an authorization but what redshop calls Zero Dollar Authorizations. We are unable to find if redshop is only doing a checksum, storing the card, then once they add shipping they out the charge through. If there is such a thing which allows this in PayPal does anyone know a woocommerce plugin which supports it?
