You might want to sell a physical media product and pair the purchase with the digital version. You can do this buy creating a listing in Shopify and using Zapier to provide the digital purchase in Uscreen.
To do this, you'll want to follow these instructions: Sell Bundles via Shopify with Zapier with one small change. When you create your product in Shopify make sure it's setup to include a physical product that is shipped. You'll want to customize the confirmation message or email to say something like, "An email is on the way with access to the digital version of your product, while another email will arrive when we've shipped."
Linking that purchase with Zapier is all you need to provide access to the digital product at the same time.
