Hi. I am new to this forum but am one of the purse authenticators at another site. I have been studying fake and real designer bags and accessories for over a year and have sold many as well. I am not an "expert" per se but I can usually tell a fake from a real.
In my personal opinion I would not buy from either seller for the following reasons:
Auction1_ On the Coach creed if you notice there is a space between the words "genuine" and "leather" . I dont believe this would occur on a real creed. The C's should be aligned on the signature bags. As you can see they are aligned horribly on the sides of the bag. She also has TONS of other Coach as well as other brands New With Tags. How can one obtain so many NWT items to sell at these prices?

I clicked on one of the Coach's she has for auction and that is one of the worst I have ever seen! I dont think Coach made such a bag. The "pleather" looks cheap and the creed!? I've never seen a creed made like that. The bag I am speaking about is the signature bag with the blue pleather trim. I'd RUN from this one!
Auction2_ The hangtag looks fake, once again same problem with the C's not lining up (which it should). Check what else the seller is selling! Same again, TONS of NWT Coach items! I dont think Coach has that much merchandise in their stores! RUN from this one too!
