Feature requests - External products support

Hi Shahjahan Jewel ,

It would be amazing if Fluent Cart could support products that link to external URLs - just like WooCommerce’s affiliate/external products.

This would let users:

• Manage affiliate products without handling payments directly.
• Connect “Buy Now” buttons to external tools like Fluent Booking calendars or third-party stores.

This small addition could make Fluent Cart much more flexible and cover real-world use cases, while keeping the current payment system untouched.

Thanks for considering!!!
