Deliver to South Africa from Chain Reaction Cycles

I would like to highlight a recent purchase from CRC. They were suppose to deliver to South Africa, I paid the delivery fee on top of the item fees. They failed to give a clear indication of the excessive additional charges. I wish there was more clarity to the charges to South Africa- customs, VAT, duties etc. It came to about 2/3rds of the original purchase price. It is very excessive for delivery and customs, without an indication to how much this might add up, one could then reconsider the purchase.
