if they haven't shipped your order yet i would cancel it, but if it has shipped, when you get it, check the model number on the stick, and look it up on samsung's website. If it turs out to be legit (ie. mass production not customer sample), which i doubt it will for that $99 price, than keep it, if not, return that piece of sh1t and get a stick from newegg, their's is the only legit one that i have found.
