I tend to agree with some of the arguments, but there is justifiable cost, and then there is profiteering
When I compare prices from my local Wholesaler, I see the item they import directly from overseas are very competitive (10-15% Higher than $ price), but the items they need to get from local agents, like laptops, motherboards and monitors, are 30-50% higher. Now I know for a fact that their margin only accounts for less than a 3rd of that price. I suspect its the local agents that are making the big bucks.
The problems start when one local agent gets exclusivity. Look at the price of apple products in SA as an example.
