You automatically have a profile with us in connection with your order. You can always view your order details by logging in with your email address on our website. However, logging in is not required, and you can place an order at any time without logging in.
The advantage of having a profile is that you can save your information, so you don't have to enter it again at checkout the next time you shop. Additionally, you can easily get an overview of your orders when you're logged in.
