No, you should ship your entire order at the same time.
We arrange one shipment per order, and while a shipment can include multiple parcels, the booking and collection of the parcel(s) will be all done together.
If you have no other option but to ship part of your order now and part later, you will need to use the ‘Self Ship’ option to arrange this independently. You can find more about self shipping here.
Please note that your order will not be marked as fulfilled until it has been delivered in full.
