Aramex Global Shopper is okay in South Africa. Although, they do not have the best customer service and often they can be a pain in the butt.
In the end, they do deliver and don't charge a lot for it. I do have complaints, such as they don't consolidate items, the packages generally take longer than average to arrive and their customer service is so-so.
But like I said, they are cheaper than most out there that I've seen; So they are worth a try, even if they are not the best mail forwarding service that there is.
In my conclusion, they are usable and I would only recommend them if you need to save some cash on shipping costs and do not need to consolidate.
