This Pre-order button allows customers to reserve products that are coming soon or out of stock, helping to build trust and confidence in the store. It replaces the standard Add to Cart or Out of Stock button, allowing customers to pre-order products before they even launch. The Pre-order button automatically appears when product inventory goes below zero, with custom messaging about availability and delivery timelines. This ensures customers never miss a pre-order opportunity and allows businesses to generate revenue before their product even launches.
