We have created a test retailer for you, which you can recognize by the crown in the retailer list.
By default, the test retailer sees all of the markers you created in the standard price line. Of course, you can change this setting flexibly. If you log in with the test retailer, you can view the stamps accordingly and also place test orders.
If you have placed an order with the test retailer, it will be marked accordingly in the backend.
