Can I sue a 3rd party website for facilitating the sale of counterfeit merchandise? For example, a seller has posted a Chanel bag. I shop on this site (like eBay or Poshmark for example), contact the seller, who assured me the Chanel was authentic and I purchase it. The site allows 48 hours to inspect the purchase before its complete. I find out later on that the Chanel is actually a counterfeit, contact the seller and the site but both say I’m out of luck. Since the sale of counterfeit items is illegal, can I sue the site?
