This is a calculator that you can place on your website that will allow a visitor to enter information and have it display a total. That is all it will do.
DO NOT BE FOOLED.
The screenshots on wordpress.org show using this as a calculating contact form. This plugin will not do what the screenshots illustrate without buying the Pro version for $50.00 per website.
We were looking for a calculating contact form that allows the site visitor to enter a name and email address, perform a calculation and then send you a copy of the calculation and send a copy to the site visitor. We looked at the screenshots and thought this was the perfect solution and didn't see the fine print stating that the contact form piece of it costs $50.
We'd likely be happy to pay $50, but after the way the developer handles this aspect, we will exhaust every other possibility, including buying a plug in elsewhere before we will use this one.
