Put in a last-minute order for an item that was needed on a next-day turnaround because my usual printers couldn't do it on time. The delivery was scheduled for the Friday morning. However my client received a delivery update on the Friday advising that the delivery wouldn't be made until Monday morning, which was too late. It transpired the print is done in Belfast and Digital Printing said they couldn't take responsibility for the late delivery because it was due to the postal service. I would suggest you make it clear on the website that the print is done in Belfast, not on the UK Mainland, as this is very likely to affect delivery times.
