Hello - I thought I would share some feedback about the plugin that might be helpful if you are thinking of using it...
I am so disappointed with the plugin because of the PayPal Standard integration issues (I used the free plugin and purchased the Gold Cart upgrade).
(1) The system does not update after the transaction processes in PayPal, so it shows payment pending and sends the ‘order pending: payment required’ email to the user. It is necessary to manually update WordPress to payment accepted. Then the system sends the ‘Purchase Receipt’ email to the user. (I also got an Instant Payment Notification warning email from PayPal.)
(2) The system sends the shipping name and address to PayPal, so if the user is shipping to a different address than the billing address, he has to edit the billing data in PayPal. These two issues make for a very unfriendly experience to the user.
I posted details on the getshopped.org forum and found another user who had the same issue. I tried numerous settings and made a few changes to some of the php files, but have not been able to fix. I will never use this plugin again :(
