Hello, this is very strange as we check AWO all the time. are you using this checkbox at the tax tab? :
Save shipping with tax in the database so it is shown with tax in the account information, order details and emails.
This checkbox changes the saved order totals and the calculation might lead to improper values when using external extensions. Which version of AWO are you using?
If you let us, i will gladly fix this directly on your site. Please send me an email to
info@rupostel.sk and i will provide you my online skype details for a quick fix.
Best Regards,
Stan
