I had purchased Tamron 18-270mm VC, PZD on the 27.03.2013 for Rs. 33500. My first order vide COD was not delivered citing various reasons. Now within 3 weeks suddenly the prices on the same lense has come down to Rs. 26999. why is such a vast difference in 2-3 weeks time. Is the price of the item much much lower that it came down so much. if so then, why the flactuation??????? Why EBAY does not put up common prices for common products of same company.?????????
