Shares of online auction giant eBay (NASDAQ: EBAY) have dropped sharply today, pushing the stock down to lows not hit in seven years.The stock, which has dropped over 20% so far this year, is down 8% on the day to $10.54. One of the big reasons why the site has been struggling has been the lack of confidence among buyers stemming from rampart counterfeiting that has been taking place on the site.
