Hi
We have paypal as payment option, and it works great, when people are actually finishing the process!
The process:
Buyer fills out the form on product page
Chooses to pay with PayPal
Gets to the PayPal page (and at the very same time get the special designed paypal notification mail)
Buyer cancels the proces
And still have a confirmation e-mail! Not good!
We have ticked off "Send notifications only when payment is received."
What else could be causing this?
