I bought a Panssonic item from Ebay and it is a fake one. The return shipping cost is?

it was a scam... dont return it as they will not give a refund... just keep the item and call your bank to get the money back

From experience, you do have to pay the return postage at first. Make sure you take pictures for your Paypal case, Paypal will eventually want pictures of the original box it was shipped in, the weight and of the item. Keep in mind that there will be an investigation and it will take some time, it sucks but that's the process of eBay trading. You will get your postage money back, when the item is not described correctly, or it is anything other than what is led to be, that voids all clauses, including buyer must pay return shipping. Again, it will take some time but you will get all your money back, unfortunately none extra for your waste of time and attention :( Stay on top of it though because Paypal will go for the easiest way out, not that they'll try to burn you but if you don't stay on top of it, neither will they! Hope this helps :)
