"Free Trial" Registrations Should Validate Credit Card Before Accepting Purchase
The "Free Trial" 1SC option when taking credit cards does NOT attempt to validate the credit card in any way, even if the incorrect number of digits on the credit card are entered, let alone whether it's a valid card. (I'm using Authorizenet as the Gateway.)
This means an enormous percentage of "free trial" registrations will be declined when a later recurring charge is attempted, which is a nightmare.
I've previously used a custom order script that did validate $0 charges (by running an "Auth Only" to Authorizenet, so I know it can be done. Not being able to offer free trials (because 1SC doesn't try to validate the CC) is a bummer.
