Royal Mail are very expensive on postal charges when sending overseas, and unless I am sending a small parcel it is much cheaper to send by courier.
Some couriers require a telephone number for the delivery address.
I have just amended my thank you message to include a note informing my customer that their item may be sent by courier and that they require a contact phone number.
Is there a way to include this request for a contact phone number at check out stage, rather than it being in the thank you message or emailing afterwards?
