amount button buyer calculate cancel cost costs emails group informed payment paypal press proceed product provided select send site update

I read the following on your site....

"Select the product you want to send out and select the buyer group you want to send it out to and press "Calculate Cost". Once you make the payment (via PayPal) using, the button provided there, the update will be sent and you will be informed once all the emails are sent."

I was curious how much it costs to send out update emails?

You will be shown the amount once you press the "calculate cost" button, then you can either proceed or cancel.
