I've looked at v1.2 that is a big improvement, but don't see a Call for Price button to avoid listing the price. It's sometimes called a Too low to show, Call for Price or similar.
If you list the price on the Internet, someone else is almost always selling the same product for less so it's a race to the bottom.
The Call for Price, Too low to show gets the prospect to call for the price and engage. That sells products, not click here to order.
Any chance for a paid add-in that provides a variety of ways to do this?
