The following have green or yellow buttons:

Authorize.net SIM
Credit Card - Offline Processing
Zen Cart FREE CHARGE CARD
Check/Money Order
PayPal Express

I don't recall having to do anything with "CC Offline Processing" last time I did this. In fact I recall it was pretty straightforward once the Authorize.net account was set up.

Anyway I tried transactions with "CC Offline" set to true, and to false. I assume I need this active ("true") if I'm using SIM. I'm going to go read up on this. I appreciate the sacrifice of your hair, for what that's worth. Sorry that I can't show solidarity, unless I yank on arm or leg hairs.
