This service is very slow and unreliable. It can take 3 days from item to be sent after it has been received at the warehouse. Then the shipping time from Shenzhen to the UK is 10-12 days even if you pay for the expedited service. You cannot plan your business as the price of fulfilment can double or treble overnight and what you get charged bears no resemblance to what you get quoted on the app
