Amcrest UltraHD 4MP 4CH Home Security Camera System with 4 x

I bought this item as brand new, never opened. I opened it myself once to check what is inside and closed. I changed my mind , as it is too many cameras for my tiny apartment and want to return them but it was after 30 days and could not do it. Original price was $365, Then it went on sale for $299 plus tax and shipping. now they are not available on Amazon and Amcrest website.
