Ha ha! I started to reply earlier (before NSP's post) but decided not to because I didn't want to get into name-calling (of the seller).
But at this point, I'll reply only to say that I don't believe the seller. She states that it's a 2 year old bag, but if she only bought it 2 years ago, she didn't buy new. it was from 2006. And I don't believe she paid $3500 though she may be telling the truth about having bought it 2 years ago. It's not a HTF style and never sold for that kind of money.\
As for authenticity, it could be authentic but there aren't nearly enough pictures to authenticate and those that are there are so blurry that I have a headache.
That said,
