I am using joomla 1.526 and vm2.02 with latest upgrade my problem is I use merchant services to process my payments and usps for shipping yet I can't seem to configure either like in the old version. Please help
as far as i know there are no modules for your shipping and payment options
you need to wait until someone develops them, or hire someone to do it
USPS is available - http://extensions.virtuemart.net/extensions-virtuemart-2/usps-detail
And there are already several payment plugins listed. eg http://forum.virtuemart.net/index.php?board=135.0
