FC Transfer -> You'll often see this on the inventory page when looking at your available stock. Units in FC transfer are being moved between Amazon fulfilment centres, to ensure that customers across the United Kingdom can all access next-day delivery for your products. If all of your units are in FC transfer, then your offer on the product listing will have a late delivery date, usually weeks away. Do not worry, this soon goes to full prime next or same-day delivery once the units have been spread across fulfilment centres across.
