Yes! But act fast, as long as your order has not yet been dispatched to our logistics partner, you can easily contact firstname.lastname@example.org with your order confirmation details for a full refund.
Cancellations are much harder after your Lumina is shipped. In that case, you will need to receive your Lumina first and then follow the Return/Refund process. Just rejecting the shipment upon delivery will not result in cancellation or refund.
