Hi - I have installed your plugin, with thanks, because my troubleshooting identified that eway.php in the Instinct Gold Cart plugin fails to send admin and customer emails. Which is really annoying because email notifications work perfectly with other gateways.
The styling of the table-2 on the checkout page was not very nice at all for my theme so I did my best to adjust it. You can see the results at http://www.buyfencing.com.au.
In your FAQs you ask to confirm if your plugin works with Gold Cart enabled - yes it does.
Apart from the problem I had with the styling on the checkout page, any orders going through WPEC are "pending" and "incomplete sales". Do you know why this is so and not triggering the complete sale?
Anyway, I'd love you to come back to me - if you do I'll be pleased to buy you a coffee :)
