TorgosPizza,

The latest version has a setting in the admin now that would allow you to only issue a certificate when the status changes to "completed", or what ever status you choose. I made the following edit in the post above:

Note: If you are having any problems with duplicate certificates (or no certificates) being created, change the last setting in admin/settings/gift_certificates, so they are only created for chosen "order status".

I hope this setting will allow you to configure things correctly so multiple certificates are not sent.

let me know.

Cheers,

Darron
