Does anyone know of some good eBay sellers who sell real not fakes?
Go to each respective brand board. You may find a thread on those boards.
Ditto the PP. Depending on what brand you want, there is probably a forum here at TPF for it.
Within most boards here is usually a pinned thread that is for Authenticating. If you find something you like, post it w/in the proper forum!
I do for Hermes - they're listed in the Hermes sub-forum in the 'shopping' section.
