ioffer.com

I also use it as a reference for fakes. I have a list of ebay sellers that primarily resell Ioffer bags. And you can usually see a rash of a particular bag in ebay when they come out on Ioffer. Ink Kooba Natasha's were abound on ebay when Ioffer came out with them and the authentic Ink ones are HTF. Same for Miu Miu Coffer bags, and Gryson Skyes.
 
99.9% fakes. Managed to wriggle out of a stupid late night ebay purchase after realising the photos of the bag were straight from ioffer. Remind me never to ebay again at 2 in the morning after a bottle of wine :shame::yucky:
 
Ioffer.com is just bad news all around. I don't think I've actually ever seen anything authentic on there before, and many of the users on there sell to each other just to boost their feedback ratings to sucker people in. I've been scammed on there before for fake Seven for all mankind and Citizens of Humanity jeans, so I wouldn't use ioffer.com unless you wanted to laugh at all the ugly fakes.
