If you bought counterfeit merchandise, and want to get your money back, there is a cerain way to do it.  Don't feel like it is a big deal, as Paypal has made this a very simple, and quick process.  Ebay makes you file a claim through Paypal, and if you report the item # for the items you bought that were fake, they (ebay) erase the transaction, so your negative feedback should go away.  When you go to Paypal, you click on resolution center.  Then you should see an option for DISPUTE A TRANSACTION.  After you click that, it walks you through the rest.  You need to report it before too long though, as there is a time limit.  As soon as you file the DISPUTE, it will give you the option of escalating it to a CLAIM.  If you don't want to deal with the seller, escalate the DISPUTE to a CLAIM.  Once you file a claim, Paypal will review your info, then make a ruling.  If they rule in your favor, you will probably be required to mail the item back to the seller WITH ONLINE TRACKING INFORMATION.  ONce younotify Paypal that the package has been mailedand give them the tracking #, Paypal will find out when the package is delivered to the seller.  I used USPS Priority mail with the tracking option.  With me it was a very quick process, and I had my full payment refunded within 10 days of opening the DISPUTE.  I would stick to the details, and avoid name calling when you file with Paypal.  If you bought anything that wasn't made by the copyright owner, then you have the same case I had, basically open and shut.  You purchased counterfeit merchandise and that is illegal to produce AND to sell.  You should file though, the seller I puchased the fakes from told me that he has sold MANY of the item I paid $70 for, and never had a complaint until me.  He is making a living selling cheap copies of someone else hard work.  Even if you don't care about the copyright issue, what are you going to do with cheap copies of dvd's (like I purchased)?  You'll never be able to resell them, or then YOU would be selling counterfeit merchandise as well.  If the seller tells you that "you never asked any questions, you should've asked before bidding," then just file the CLAIM, and tell the seller that "you shouldn't HAVE to ask if something is real, or a fake".  That is implied when you purchase anything UNLESS it clearly states in the ad that the item is a COPY.

This should help, but if you have any other questions, feel free to email me.
