Take a look in service duscission. Look at how many times such a question have been asked for different sites and you should get your answer in most of the threads that people have posted a reply to. There is just way too many of these fake sites out there man.

Just take a look at their site, does it look particularly legit for you? They have a chinese address as well, so how are you going to file a lawsuit against them in case something goes wrong with your purchase?.

Purchase from a reputable reseller or official seller, do not purchase from some site that you found on the internet randomly by seraching. It's good that you're asking though, otherwise you could be getting scammed in the thousands.
