My stance is a little different. I still think that CBSubs is amazing and does everything I need it to and more. I have my site live, with AVS disabled in the backend of my Auth.net account (just as dirtypants posted above), and everything is working perfectly. Since CBSubs is fairly new, I understand that there will be updates and I will be taking the hit for add'l fees until they can resolve the AVS issue. My thoughts are to make it work and build up traffic to my site until the fix is made available. Hope it is very soon!
