May I add some of my friend experiences?
My friend bought an authentic bag from a seller in eBay, then she found out afterward that there're some people who had the same pictures and same description of the bag she bought. So, she emailed the seller of the bag, and then the seller report that to eBay because they're actually her pic in her house.
My point is may be the bag is authentic and posted somewhere before, so it might not the bag that this seller will actually sell because the seller might get the picture from somewhere else.
**my post may a bit confusing, I'm not good telling story**:shame:
