Hi @Jennifer Russo Galvis,
Welcome to the Dyson Community, and congratulations on your new Dyson Supersonic Nural hair dryer!
I can confirm that it’s normal for promotional items (such as a free Presentation case) to be packaged and shipped separately via a different courier or mailing service.
It should be delivered to you shortly - within 3-5 working days following your order being processed. But if you do have any further concerns, please visit Dyson.com and click Support to get in touch with the right Dyson Customer Care team for your region so they can double check your order status for you.
Hope this helps!
