Why can’t I order my delivery for 09:30? February 25, 2020 To enable us to offer the most efficient service around campus and to allow for the most delivery slots per hour the delivery options are every 20 minutes. (e.g. 09:00, 09:20, 09:40 etc.). If you require the delivery for 9.30am we suggest that you book it for 09:20 where possible.
