You can either cancel the whole order or just the one item that is not available. For that, you need to already specify during the order process (i.e. when completing the Concierge form), which of these two options you choose (the whole order or just the unavailable item will be canceled by us).
Already paid fees will be refunded to you 100% on the way as you have paid for them.
We will notify you if and why an item cannot be ordered. We will also ask you if you want us to order this article for you at a later time.
