Follow these steps to add estimated delivery time (EDT) to products on your Shopify storefront:
Step 1: Go to your Printful Dashboard and click Settings and click Shipping. Scroll down, and press the Enable access button under Estimated delivery times (EDT).
Depending on when you connected your Shopify store with Printful, or if you've started the EDT enabling process but never finished it, you might not see the Enable access button. If this is the case, you can go straight to Step 3. 
Step 2: This will redirect you to Shopify. There, click the Update app button to give Printful permission to show estimated delivery times on your Shopify storefront. You will then be redirected back to Printful's shipping settings.
Step 3: Under Estimated delivery times (EDT), check Show EDT to your customers on your storefront, and press Save.
Done! Now your customers can see estimated delivery time right next to the products on your Shopify storefront!
Note that EDT will be shown only to your customers in the following countries: Australia, Austria, Belgium, Brazil, Canada, Czechia, Denmark, Estonia, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Republic of Korea, Latvia, Mexico, the Netherlands, New Zealand, Norway, Poland, Portugal, Singapore, Spain, Sweden, Switzerland, the UK, the US.
A little something extra:
We automatically match the design of the EDT feature with your Shopify storefront theme. But you can also play with the design yourself—if you uncheck Match with your storefront theme under Set EDT visual preferences in your Shipping setting on Printful, you'll be able to edit the color of the EDT message.
