You have a checkbox for: "Send admin notification only when payment is received". I check this because, after payment is received, the user gets redirected to a download page to download the item she purchased.
I would like to get an additional notification: "Also send admin notification after form is filled in" i.e. before payment is received . This will tell me how many users got as far as filling in the purchase form, but failed to complete the PayPal payment. This will be very useful - it will also tell me if my PayPal payment system has failed for any reason.
Can this be done?
