I've been using IPN. I haven't tried enabling both IPN and Express Checkout.
I believe that I am losing business because of customer resistance to setting up a PayPal account. And, they view the PayPal on my sites as requiring the paypal account. Some customers don't get it that they can use IPN without a PayPal account. How do I enhance my site to train them into using paypal without an account? Or, should I use express along with IPN? I don't understand your redundancy statement.
I've also read about a better paypal graphic to entice customer to use IPN without paypal account. What/where is it?
Thank you,
John
