The Cart goal is the amount of money you encourage your customers to spend before they receive their shipping discount. For example, if you’re offering free shipping on orders over $50, you'll want to place that number in the Cart goal field.
This amount will display in the bar for customers to see, and will decrease as customers add products to their cart, indicating the amount remaining that they need to spend in order to reach the free shipping threshold and receive their discount! The currency will match the currency settings of your Shopify account.
Note: the app will show $50 as a default amount, rather than pulling in any information from your shipping settings. Make sure this number accurately reflects the goal of your bar!
