Looks like a scam site?

Why would you even bother wasting our time to ask?
A Sony PS3 for £100? Does that sound legitimate to you? Do you really believe that you can source that sort of premium product for several hundred pounds lower than the actual retail price?
Its just simple common sense and a serious lack of any at all is the reason why so many of the general public (like you) get scammed.
A little reading and research goes a long way, and its all here for you, you just have to be bothered to read it.
