In the previous step you clicked on the "1-click Package" option and the record of the Package was created automatically. You can see the Product's record you created attached to the Package's record.
You will also see that the Title of the Product's record has been inserted automatically as the Title of the Package. You can change the Title if you wish. The Title of the Package will be displayed to the customer in the order form.
Next select the currency you want to use.
In regard to the "Customer's receipt":
DELAVO will send the "default e-email" to the customer as receipt of the purchase. You can customize this e-mail by selecting the corresponding radio button (not suggested.)
Once done, click on the Save button to save the Package's record.
You just set up the record of the Package. 👌
You can repeat the process if your DELAVO plans allows the creation of more than 1 Product/Package records.
