Hi,
I'm using the PayPal IPN v2.3.3 module. In our shop we use a flat fee for shipping. Still, when a user buys 2 items, he gets double shipping costs charged in Paypal while in OsCommerce the buyer looks at his bill with only single shipping costs (as it should be).
Secondly, with orders with two of more lines, the processing of the call-back from Paypal acts differently.
Somebody knows how to handle this problem?
Regards,
Ronald
