No need of credit card if it's a $0 checkout

What's New?
Business users can now allow end customers to check out free products without needing to enter credit card details.
This feature is supported on both one-step and two-step order forms, as well as in online stores.
Users can enable or disable the free checkout option from the Funnel Builder settings.
These settings also apply to upsell purchases.
Free checkout is available only for one-time products priced at 0 or for recurring products that have a 0 price for both the initial checkout and future billing cycles.
