We ship your orders from various international warehouses (US, Canada, Malaysia and Singapore). Our stock is spread out over multiple fulfilment centers in order for them to get to you faster. This means orders containing multiple items may be shipped individually. You may receive one item before the next. So don't panic if you don't receive all of your items at once…they are on the way. Therefore, the partial shipment could be applied to customers’ order.
Items from an order that ship separately may receive different tracking numbers. If a certain item is not associated with the tracking number that you have, that item has most likely not been processed for shipping yet and will probably receive a different tracking number.
