This function in the Product Detail page allows you to set the estimated date that the shipping unit will deliver the product to the customer.
Each product can have a separate estimated delivery time, accounting for differences in goods and order volume.
From your WP Dashboard, Go to Rising Bamboo → Setting → WooCommerce
Turn on/off this function with the slider "Shipping Estimate Time."
Estimate Time Type: Day or Hour
Set the estimated time in each product's properties. You can set this when creating a new product. If the product is already available, please click "Edit" on the product to set this value.
