Delivery & Shipping

We value your interest in John Zack. Your new garments should be delivered to your home in perfect condition, but if there are any challenges along the way please read on carefully. Below you will find detailed information for our shipping and returns procedures.


You will receive your order anywhere from 3 to 5 business days from the date the order is placed. Orders will be shipped via Royal Mail. An individual semi-tracked number will be sent to you once your order has been shipped, so that you can follow the status of your delivery. 

If you do not receive the number, please contact us. 

Please note that we do not dispatch orders on Saturdays/Sundays or Bank Holidays.

Although we would love for you to get your order as soon as possible, orders made over holidays such as Christmas and New Year’s may be delayed as after your payment is authorised and verified, it can still take up to three days to process your order.

Please note that in order to avoid disappointment we recommend you purchase UK Next Day Delivery, if you require a garment ASAP or for a specific date or event.
