Disappointing Takealot Service

Yesterday I purchased a Canon 100-400mm f4.5-5.6 L IS USM telephoto lens from Takealot for a good price. I was not surprised at the price as Takealot is well known for their specials and products on offer.<br> I purchased the lens through a friends profile as he was also purchasing the same lens. The transaction was successful and the money was deducted from my account.<br> I was so excited about lens and the service from Takealot but that soon changed dramatically. Later the afternoon I received a call from my friend saying that he had received a mail from Takealot stating that they could not complete and deliver the order as there was a \pricing error"and cancelled the order. My friend's order has also been cancelled.<br> Will Takealot have \""pricing errors\"" again for every special they run on products?<br> Must I warn people against specials on Takealot"
