Yes, you can. Note that all buyers have the right to cancel their order any time before shipment, and are able to return art 7 days after the delivery date if unsatisfied with the work. (For more information regarding our return policy please see Vango's 7-day Return Policy)
In light of our 7-day return policy, we recommend that you please allow the shipment to arrive so that you can see the work in person before making your final decision whether or not to keep it. However, if you're absolutely certain that you do not want the artwork after all, please immediately contact firstname.lastname@example.org and provide your order details.
