Jason, in reference to the shipping, enable shipping is checked in the admin settings and my shipping table is set up. <= 1.00 lb is $6.95 and the weight of all of the products are set to 1.00 weight in pounds. Go to this item, for example, and add it to your cart and pretend to go through checkout. products_detail.php?ProductID=28. Shipping is not added prior to PayPal. Is this the case with PS4 - that shipping will not be calculated until AFTER a PayPal payment?
I have asked my client to look into her PP credentials due to the error message.
