Hello, just posting a message here.
The order confirmation/Thank you page doesn't show any totals, it only shows the items/products in the order, no totals. To see the totals the customer must go to the 'Orders History' where they can also see if a discount was applied or not.
I've just added to the development list to have this configurable so that you can dd totals, sub-totals, coupon code and so on to the order success page.
It would be great if you could submit questions/requests like this to our help desk http://tribulant.com/support as the forums aren't regularly maintained by admins, it is intended for community discussion.
I hope this helps, you can look forward to the features mentioned above to be available in the near future.
All the best!
