Recently I bought two 2GB flash disk cards from Alibaba marketplace (first and probably last time from Alibaba marketplace). The packaging looked poor compared to 2 other 16gb sandisk microsdhc cards i bought a couple of months ago from play.com
So I thought they were fake and contacted Alibaba and the marketplace seller. seller insists it is genuine and Alibaba just fobs me off (inspite of phonecall and messages) to contact seller even though Alibaba obviously gets a cut from the Alibaba marketplace sale i guess.
