Why do you need to see a description or a copy of my leaflet design if I am using the 'distribution only' service?

This is to ensure your leaflet is not competing with any other company's leaflet offering a similar product or service as you, at the same time and in the same area as your distribution. If you have provided a description only, please note that we will need to see a copy of your design at least three weeks before your distribution is due to start. Please send a PDF of all sides of the design to leafletdrop@whistl.co.uk. Your order is at risk of being cancelled if we do not receive this on time.
