Hi teddybairre60,
Thanks for inquiring about this. I just checked with our engineering team regarding this matter and am pleased to report that we expect to have "Propay" added to the available payment options on the Auctiva lister page with our upcoming site update that will take place in mid/late January.
If you have any additional questions or concerns, please feel free to contact our customer support team using the web form on the following page: http://www.auctiva.com/help/requesthelp.aspx
