I’m not sure if this is the right place to post this so apologies if it isn’t.
I’m writing about an issue with discount codes and the DirectOne extension (http://www.magentocommerce.com/magento-connect/securepay-directone.html). We are using the newest extension version.
The domain is http://gtdd.com.au/shop running Magento 188.8.131.52. The plugin runs fine for regular price items, but when we use a discount code (eg. “GTDDfriend") and checkout, the price on the securepay payment page goes up (by the discount amount) instead of go down. When you try it, you must use an Australian address as we only ship there.
I emailed SecurePay and their response was:
This looks like a bug in the way the Magento module is written. Because it is Magento that host the module and pass through the discount amounts to Direct One, you will need to contact them to rectify the issue.
So here we are, any advice on how to debug or fix this would be much appreciated.
