One of the most unprofessional companies I've ever worked with. Their pricing isn't very transparent, and they get you with hidden costs. Customer service is non-existent, would refuse to cover insurance for lost parcels. Honestly, the list goes on but one could probably write a novel as to why. This is all coming from personal experience.
There are way better alternatives with better professionalism than these guys. We switched fulfilment companies shortly after and haven't looked back since. If I could give them 0/5, I would.
