For in-stock items, we are happy to accommodate changes or cancellations before the order is dispatched. However, for non-stock items that require special procurement (such as branded printer printheads), changes or cancellations are not possible once the procurement process has begun. To avoid any inconvenience or misunderstandings, we kindly recommend confirming all details with our sales team before making payment. This helps ensure a smooth transaction and prevents unnecessary delays or disputes.
