**4 iPhone 4 8gbs to sell** All perfect condition in original box** Together or separately ?

Hi, I have 4 iPhones to sell that are 8gb. Two are black and two are white. I can sell them separately for 200 pounds each or if you buy all of them I would be willing to let them go for only 185 pounds each meaning the total cost would be 740 pounds. Feel free to ask me any questions. Thanks
