Of course you have the possibility to cancel your order (should you mean cancel in this context, as is still colloquially said).
The cancellation period is 30 days after receipt of the goods. You must inform us of the cancellation in writing, e.g. by e-mail (email@example.com) or by post.

If you mean cancel in the sense of "stop of the delivery", then unfortunately this is not possible.
You can find more information in the article "Can I cancel or exchange individual items from the order?"
