It is always advisable to keep all items in one order in one parcel, and to create seperate orders for each box.
If however you cannot fit all of your items into a single package, you can create a new postage label with a separate tracking number by using the relevant link below:
For Royal Mail click HERE
For Collect+ click HERE
Please ensure that you enter the same order number correctly on both labels and annotate with the number of parcels ("1 of 2", "2 of 2" for example) to ensure they get put together by our team when we receive them.
Please note: You cannot use the same postage label more than once! Please ensure you create a unique shipping label for every parcel you send us.
