I have worked closely with Greatrex Marketing for over 9 years and can honestly say that their product knowledge, product sourcing, and ability to get the job done is second to none. Whether the job is large or small Darren will ensure the same quality and attention is given to ensure the products are done properly and on time. Wouldn’t trust anyone else with our company’s reputation.

CODAN Australia

Darren has been amazing, he responded to our request to fit all of our 400 staff for winter jackets and vests sporting the Codan logo at very short notice and delivered a quality product within very tight time constraints. Darren also professionally managed the project from start to finish, providing regular updates along the way.
Based on this success, we have asked Darren to help us with our upcoming charity golf day and he has supplied merchandise that will be distributed on the day and is helping us plan and manage utilising his experience in this area.
