I am in sales line. Price war is what i used to see everyday. Some high, some low, some at public price(which most people buy and sell), we call it market price.
But I think at whatever price, the buyer buy the goods willingly. He must feel that he need that item at that moment and he can afford it, valued it and agreed to the price.
It is not fair to complain the price after the trade is complete as both parties agreed the deal.
If you wish to buy things at reasonable price, do some study before buying lor.
If you are buying used part alway can check what is the price for new set then evaluate yourself.
