I asked for next day delivery and was never warned that that may not be possible. The prints arrived 3 days late and are not needed now. It would have been helpful to know that my request of next day delivery was not possible before I went ahead with the printing. I now have to pay £30 for unwanted printing.
Strengths
Literally none. Bad website. Bad communication. Use of invoice as payment.
Improvements or suggestions
Payment and shipping method. Communication.
