To test the app, you will need to create a test customer account. Create a test customer by entering an email address and password on your store’s account page.
Once you’ve registered a new account, log in to your Shopify admin to tag the test customer account with a customer tag.
When tagging your customers keep in mind that these tags are treated as case-sensitive; copy it exactly so they match. For example, if you enter "wholesale" in the app, do not tag customer accounts with "Wholesale".
