How did you pay for the bag? I always use a credit card with Paypal. When I have a problem with a fake item, I immediately call my credit card company and open a dispute. They refer to it as a "chargeback" and since it is for the total of the charges, including the cost of insurance and postal fees, I only pay to get it back to the seller. If the seller gets nasty and refuses it, the cc company will automatically issue a chargeback. If it is received and the seller tries to issue a "partial" refund like less the 20% restocking fee, just call and explain to your credit card company that the item is fake and the 20% doesn't apply. They are your bet when navigating eBay. I also immediately open a dispute with Paypal, and follow up with a call directly to them to check status. Paypal is rather lame when it comes to investigating claims. I open a claim to increase my chances for my refund. Do not be intimidated by sellers. Without buyers, there would be no eBay. Good luck!
