I have a couple of important questions regarding selling on ebay.
1. How excactly are you supposed to pay your ebay fees, where to find information about it and how is it done? I have sold a couple of items with a fixed price, but, to my knowledge, only paypal has taken it's taxes, while ebay hasn't. Where could I find info about my debt to ebay and how do I pay it?
2. When I tried to post a second item on ebay, it gave me a warning, that my listing would be checked and that I was highly recommended to show proof that the items are authentic by writing a serial number or showing some kind of a certificate. The problem is, I am selling perfume, and the serial number is located only on the bottle, so, in order to see it, I would have to open the box and it wouldn't be "new&sealed" anymore. And I don't get certificates, because I do not get my items in such big amounts to get them. What could I do to prove, that the items are legit? Would a picture of it be sufficent?
Thank you very much for the answers in advance, I know these questions are probably noob, but I'm just starting off and it's a bit complicated
