Hi I used amember years ago and I was able to set up one click upsell payment after check out using NMI as a gateway. My question is, I now have paypal payments pro and I am hooking up amember to a custom check out page for my site and I would like to set up a one-click upsell after the customer presses the paynow button. I like to offer customer 3 packages to chose from after the check out page. Can this be done using the new amember software and paypal payments pro? without having the customer to re-enter cc details or redirecting them to paypal
