The “Call for Price” addon is very easy to configure. You just need to choose a calling type and add your number. So that, all the products of your store that don’t have a price will be showing the calling button.
Call for Price Button
This add-on lets you add the call for price button in the place of price and hide the “add to cart” from the product pages.
You can choose any of the three available types of calls, Phone calls, Skype, and WhatsApp by which the customer can call you to know the price.
