title: WooCommerce, manually add a product and price for purchase
body: <p>I'm trying to figure out if there's a way to use the WooCommerce Cart and Checkout functionality if I need to purchase something that isn't technically a <code>product</code></p>
  
  <p>In other words, it's a completely independent "membership" that needs to be purchased, but isn't a product post.</p>
  
  <p>I'd love to be able to add an item in the cart manually ... manual name, manual price, manual meta data and then purchase.</p>
  
  <p>Does anyone have any idea how to do this?</p>
