Excellent product, very efficient order handling. Only reason for reduced score is sub standard courier choice. No ability to modify the delivery, or choose a timeslot for recording delivery, won't use a safe place or redeliver to a pickup shop and the "local" depot was miles away. All things considered, the efficient handling of the order was completely negated as it was 5 days later and £10 of fuel to get my delivery! Please consider using a better courier eg DPD, where there is much more flexibility and live monitoring/ tracking.
