Yep, I know Fisch for the Hip. She *used* to have more reasonable prices for her bags, and in fact I once bought a Rouge Vif Birkin that was brand new from her, for slightly under retail. I sold it because I didn't carry it too often--being bright red. But now I kind of wish I still had it, because I will never replace it for what I paid. I certainly won't buy from her anymore now that her prices are so much more expensive (and her staff is occasionally snooty, but that's really neither here nor there).
She usually does have NEW bags, though--only occasionally is she asking $10K for a used one, and I just think that's a little nuts. But she charges her consignors 50% so the bag owner is only getting $5K out of the deal. I can see why they wouldn't take less.
