The item(s) within your order including samples are not guaranteed for fulfillment. During the time of order processing, it will be determined whether an item(s) within your order needs to be cancelled due to stock availability issues. We will ship the remaining available item(s) within your order to prevent shipment delays. Should your full order be cancelled, the pre-authorization hold will automatically drop from your payment method. Please note that cancelled item(s) including samples cannot be replaced with an alternative item(s) once the order has been processed.
