Item more than double priced

I am looking for a compressor. I looked under takealot as i buy from them the items that are not available in my area. I trust that i will get a good deal and they have a pick up point in my area. I could not believe that a 100 litre compressor cost R21000 and went to google. There I found eactly the same compressor adverised by Makro for R8500. What a huge difference....and then takealot just say that they are not selling and a third party does. We as public buy from Takealot and they should atleast make sure their customers get a good deal and are not ripped of. We as public buy from takealot. If you want to buy something... somebody will refer you to takealot. We buy from Takealot.
