Authentic?? I've never seen this one before...
eBay: 100% auth Coach Black White Summer Bag Purse NEw RARE (item 250080507799 end time Feb-09-07 10:02:46 PST)
I would stay away simply because of the seller's attitude. Why in the world would a seller not answer questions related to authenticity ? I think its a shady auction simply because of that. Ofcourse, the fact that she doesnt have a clear pic of the authenticity patch, no categorization of this bag as Coach in the item specifics and no mention of the style number makes its incredibly risky to bid on. IMO, it could be a fake.
