I tested Stripe (It's FREE, same Fees like Paypal. But in Abantecart website, i see only payment by credit card, not like Paypal by Email if someone has already an account with Stripe) and the client never receive confirmation "Information provided below will be visible to your customers. Use this to provide support specific contact information." I go to settings--->Mail and i coched all case.
Do you have another Payment module who confirm shipping (Security is very importnat before start shipping).
Thanks.
