Hello,
we are an animal welfare project and want to sell spay&neuter vouchers.
Our clients buy one or more voucher and get mail with unique serial number for each voucher. I cant find a solution for virtuemart. For Hika Shop is an extension like hika serial but Hika is not our first choice.
Simple: http://awodev.com/products/joomla/awocoupon
no "thank you" button here :-D so i have to write
THANK YOU!
