I won the best offer for this marc jacobs bag, and I know I shouldnt have made an offer until I was sure it was authentic... but I asked the seller (who I have been emailing back and forth negotiating the offer) for more pics, she sends me an invoice but does not respond at all to the additional pics. And I know she has to be there, since she sent me an invoice afterwards... what should I do? What kind of repercussions are there if I end up not paying (which I dont think I'll do, I may jut pay and hope for the best?)... Ack, I dont know.
