Hi Rizwan,
Thanks for oyur plugin. I am experiencing the same problem as Korg74. After payment the summary page is not showing subtotals correctly (all decimals are rounded to zero). The same thing happens on confirmation emails.
If you try and pruchase something (you can select pay it with bank transfer) you will see it: http://www.pcorredera.com/
All delivery fees are simple, and I tried using both dot (.) and comma (,) to separate decimals but none seem to work. If I deactivate your plugin it works fine.
Thanks agaun for your time.
