Deerpark, I would agree with you that caution must be exercised when purchasing on ebay. But, the feedback system and feedback rating used by ebay is an effective tool to help buying make decisions and, in this case, I think one does not have much too worry about. This seller has accumulated 2457 feedbacks, with a 100% positive rating. And, if you look at the details of the feedbacks, you'll find where customers have already bought 8GB flash drives from him and left positive feedback. So, he looks like a trustworthy seller.
