I'm looking at purchasing one the few copies of CS6 that I can find. I found a place called King of Software. They are listed as an Adobe legit certified reseller...but has anyone bought anything from them or can anyone verify their legitimacy?
Well, don't know about that one in particular, but you really have to check Adobe's verified list of official resellers/partners:
If you don't find the name there, then it's highly likely you would not be getting genuine product.
Be really careful with who you give your hard-earned money to, and what you allow to be installed on your machine; there are so many scams out there... If the software is not coming from a vendor whose name you already know, recognize and trust, then in general it's a bad idea.
