This site has been registered for more than a year. Typically scammers do not register a domain for more than a year.
WE cannot tell you that this is a legitimate website. We do not make recommendations regarding websites or web sellers. If you are in doubt, it is good to be cautious. Personally, I do not buy from sellers who do not have a store front presence, where I can return items if there are any problems.
If they want payment by Western Union or any other money transfer service, you can be sure it is a scam.
