Hi guys, I have accumulated a lot of bags last year and want to start recooping my money. Is there anything I should be careful with - any helpful hints to protect myself as the seller? What kind of security locks can I put on my bag (where can I obtain them) so if cut - it is unreturnable. I don't want to sell and get a fake back either. Regarding paypal - any hints there? thanks for ANYTHING you could forewarn me about! I truly appreciate your time and knowledge.
