why isn't shipping cost shown on total amount on form?

I set up shipping rates, but when a product is selected the form only shows the total for the product and doesn't show what the shipping cost will be. I really don't want to surprise my customer on the checkout page when they see there is shipping fees. And I don't want to have to clutter my form even more with a message telling them how much shipping will be and that they need to click submit to see what shipping will be. How can you make this happen?

Hello toledobanners,

Currently, the shipping cost feature is designed in such a way that it is only added to invoice when you are redirected to the payment page. Please check the screenshot below: 

Unfortunately, there is no other option to display the shipping cost within the payment question before the page is submitted. Only option is to add "Shipping Cost" as a new product and make it selected by default which you have already done in your form.

Thank you!
