When you hide prices in your store, a product listing page in the storefront will display products for all customers as follows.
When hovering a mouse over a product, the "Request for price" button will appear.
This button also displays on the product details page.
When clicking the "Request for price" button, a customer is redirected to the "Contact Us" page.
Here, the customer can use the filled-in form to inquire about the product price. It will only be required to specify the name and email for guest customers there. The registered customers will have all fields filled in. If necessary, the sender can edit the default message title and text.
The email will contain a direct link to the product requested.
