It is currently NOT possible to GUARANTEE a delivery date, sorry! In this industry, it is better for us to be honest than to let a customer down.
Currently, all systems sell with a lead-time. We manufacture and test systems, and a new batch ships out approx once per week. At present, all systems are pre-sold to approx 4-6 weeks in advance.
Sorry that we can't do any better today, but we're working on it!
Note: Until we have increased production to a point where we hold stock rather than manufacturing to order, many lead-times will vary, please see product pages on the website for an approximate delivery time scale. We do our best to keep these pages updated but if you need an order for a specific date please let us know!
