Courier fees depend on various factors:
Weight of product
Weight of total order
The website automatically takes all of this into account once you checkout and will give you a shipping fee.
If the system is unable to do this, it will tell you that the shipping cost needs to be worked out manually and once order is placed a sales person will email you the shipping cost for your approval.
As a rough estimate it is usually R90 for first kg and then an additional R5 for each kg thereafter.
