Need help setting up physical "store" page

I am newer to Word Press (well - no paid training - just google trained). I am trying to set up the commerce on my site.

The problem I have is how to create the physical "www.videomantis.com/store" page. I don't know how to create the page that all the products live on... I appreciate any help you guys can give me. I would love to be able to finally complete the entire process myself! Thank you!
