I've been all over the website- are there recommended prices anywhere? Preferably NOT as part of a video?

First, I DO NOT have an Etsy shop so much of the learning parts don't help, no integration. I have a WooCommerce store on WordPress .com TY ahead for anyone who can help unconfuse me. So I set my price and my print margin will just be different depending on the country a poster is going to? When I place an order and fill out the customer info for shipping will the customer get any order confirmation? Or anything about shipping or tracking? Or will that come to me and what I send to the customer is up to me?
